An apparently defunct question risen from the dead! Actually I thought the 4 wheelers might have lasted into the early 30s, as on the Golden Valley. Do you know what variety of non corridor composite, and I wonder would the brake van have been the main Kington one (an AA13 road van IIRC at some point, but I don't remember it's dates offhand)?

Piece of music - Bach flute sonata in B minor BWV 1030 (Period instruments only please) Song - Dowland "I saw my lady weep" Campion "Western Wind" Dylan. Desolation Row, Visions of Johanna? Leonard Cohen . The Traitor, Anthem?? Kinks Sunny Afternoon. Almost any aria from Bach Cantatas where voice and flute (or oboe) duet. Album. Haydn. String Quartets Op. 33. Might pick differently tomorrow though.

I went to a Grammar School too. As my hair got longer in the late 60s the head told me "you'll end up playing the banjo on a Cornish beach" (banjo????). About ten years later I lived quite near a Cornish beach (Porthtowan) and played the lute (badly). So he wasn't that far off. Hair was still long though, so there. (Where did it go?)

Further to this, would it be technically possible for the two exhausts to join on the tank top and run in a single, common pipe to the smokebox?

Sorry, I misinterpreted his comment, it obviously just meant that a locomotive with air brake only could not work passenger stock on a vacuum braked line, just unfitted freight. Thanks for your clarification.

PS, just as a matter of interest, Flying Pig mentioned passenger trains, if a minor line (not vacuum using S&M) had stuck with air brake (as I believe the LBSC did) is there a date after which they couldn't use that for passenger work? (I think the Bishops Castle used even ancient chain brake until about 1923.)

I must admit the more I look at this the less I feel that I understand the pipework on any of these three enough to make a model. In the Hecate picture above there is a small pipe coming from the middle of the cab front and down, and seems to cross to the near tank top between whistle and dome. This seems the likeliest candidate for vacuum exhaust. Also what I think is exhaust from the Westinghouse pump goes up on to the same tank top. At the front end I think there is a pipe running to the smokebox just above the handrail. Presumably this the other end of one of those two, but which?

According to Johnson's history of the line all three were fitted with vacuum brake, though the pumps were not removed. There aren't many photos but Dido seems to be the only one with the obvious exhaust from the ejector.

I see what you mean about the small pipe, if it is an ejector where might it run to? I can't see any sign of it getting to the smokebox.

I have read, but can't search for where just now, that those two kept the pumps even after they were used. Looking at that picture before I thought I saw a vacuum pipe on the front buffer beam. Though the question of passenger use wouldn't be crucial.

Thanks again for your help, I'll study the article, and then must decide whether to go for this pipe ( on Dido), or the condensing pipes (on Hecate or Daphne).

Thanks again. Actually I had seen that picture, I guess the whole red-handled control the other side of the window (spectacle?) operates the exhaust, and a pipe runs up to that from somewhere below? Yes, Becasse, having also GW interests I am reminded of the variety of the 517 class. Unfortunately the Shropshire and Montgomery three vary, though all A1, and there's only a couple of often poor photos of each, so one must try and fill in details from elsewhere.

I'm a bit late to comment, but you have Shropshire and Montgomery under A1X, surely all three of theirs were A1?

Of course, thank you, I feel a bit silly now. I have found some more pictures giving some idea of its course and fixing, but not so clear about what happens to it inside the cab. Presumably it would rise from the braking system?

Thanks for the answer, you don't know of any helpful pictures for its route and fixings? Actually would an exhaust run through the cab front into the cab?

Not being a Terrier expert (I just want to produce one of the S&M three) I don't have the relevant books,so maybe some kind specialist can help. Two of those three (all A1) have the condensing pipes from front of tanks to smokebox, the other has a pipe one side from high on the smokebox, between handrail and chimney, back along the boiler and angles up into the outer edge of the cab front, level with the window. What is this, what happens to it in the cab, how is it fixed along the boiler? I have searched online but can't find a good picture of the back end of this pipe.

Has anyone built one of the above kits? I want an Ilfracombe (to be S&M Hesperus), I could get the Branchlines kit, but some don't seem so keen on that anyway and I prefer brass to whitemetal if possible. So is this a truly dire kit, or one of Jidenco's better efforts? They do vary I think. If it's the latter I'll keep watching eBay for one, I missed one a few months ago.

I've been thinking of a new iron to go with my old 25w Antex, but I'd want two things from it that may not come together (or not at an affordable price) First, temperature controlled, but going low enough for whitemetal soldering, those above don't seem to go below 200 degrees But also something like 60w, for when joining something chunkier than etches. Any ideas?

As you were, I have acquired the missing pages.

Yes, switchable like my Compspeed F which started all this, but I still don't know if feedback off means straight DC or still something that a coreless may not like. maybe there was an answer to that in one of the more technical posts which sailed well over my head.

I feel much the same, for me the main point of modelling is making things so I'd probably spend a lot longer looking at a finely modelled static scene than something less well done but with movement. Certainly I've spent a lot more time at Pendon looking at cottages and landscape than at moving trains. Just personal taste.

No idea. Certainly my Terrier (when I eventually build the thing) will just be creeping around a small light railway cameo sort of set up so I doubt it. Some of the posts, I fear, exceed my electronics comprehension, so I'll get on and build her, and try it with the Compspeed F with feedback off (when it may or may not be pulsing), and with the lower feedback setting, and see. If I'm not happy with that will maybe try a simple modern non-feedback controller. Does anyone have any opinion about the Gaugemaster Combi in that role if it comes to that. Thanks to all who have contributed to the question.

I have just bought an Albion Terrier kit on ebay,which arrived today. The parts seem find, etches still wrapped, but the instructions refer to a diagram, or diagrams, for the body construction and the only diagram that came with it is for the chassis. Does anyone have a set of these instructions lying around who could kindly scan me the missing bits?

Sorry, maybe it's because it's late or maybe I'm just dense regarding this subject, but you seem to be saying that there are pulses whether feedback is on or off (just varied according to back emf if it's on). In that case though why do the Bodmin Compspeeds work better with the Portescaps with feedback off, if it's still outputting pulses anyway?
