Not so sure it was a later modification - all steel framed RCH drawings that I've seen up until 1927 have a racking plate.

 

The number of holes varied but they all seem to have one with only wooden framed vehicles and the later 1927 variants (with a revised layout for the frame members) not being so equipped.

 

I'm not saying there were none to the same layout as the Oxford item but generally I would have thought there would be more vehicles in service with than without.


Excuse my ignorance, but what is a “racking plate”?

That's a new one on me, too.

 

Looking at the photo, there appears to be a sort of shelf inboard of each end cradle on the wagon next to the loco, that the second one doesn't have, so I think that's probably it.

 

If so, it shouldn't be too difficult to add where necessary.

“racking plate”

 

The oblong plates that are riveted (or welded) across the end of each frame above the buffers and drawbar to counter frame twist.

 The racking plate can be seen on the image posted by Porcy Mane on the wagon closest to the train engine - it's a metal plate that fixes to the headstock and sole bars and can just be made out to the left of the front and rear tank retaining bolsters (which are shorter in length than the two central saddles).

 

I believe the purpose of them was to keep the headstock and sole bars at 90 degrees to each other and the term 'racking' simply means something going out of true.

 

The drawings I've seen for steel chassis equipped vehicles all seem to have them until those for 1927 at which point the frame was altered giving added strength to the build.

 

RCH specifications for 1907 show a ten hole rack plate modified in 1911 to four hole (not sure if the holes were for weight reduction, component access or to avoid pooling of product).

It is an early post war repaint as it has the wartime sm prefix which later repaints did not have.

 

Ok thanks. I'm looking for livery from pre-war, 1930's.

I've found a resource listing a vast array of liveries:

You have to scroll down a bit past the industrial section.

 

Treat with caution - by the author's own admission, the information is somewhat generalistic and may not be wholly correct / accurate.

I don’t know about era but I think maybe about the same as other liveries?  Which I think is pre WW2?  
 

By the way, this more recent post from markw  seems to suggest “Shell” on one side and “BP” on the other - the wagon number is the same on both vehicles, I.e. different names on different sides.  markw also refers to a Shell Mex & BP version (singular).

 

 

There are pictures in British Railway Private Owner Tanks Wagons (Railways in Profile Series No.14) R Tourret Cheona Publicatrions 2001 (ISBN 1 900298 17 1) of no.s 1500 and 7004, both 14T Class A, with SHELL on their side with the comment that it was probably BP on the other side - 1500 dated as 8 March 1952 at Eastfield and 7004 25 May 1956 at Starbeck

I think I’m stepping into a minefield here so here goes; the buff colour was introduced for class A tank wagons in 1907.   In 1939 the livery was changed to the silver grey livery with red solebars but almost immediately changed to a dull grey for obvious reasons.  The silvery grey livery was reinstated post WW2 but the buff livery lasted for some time as BR allowed companies to use it as an alternative into the early 1950s.  As for the pictures of the ShellMex BP tanker it’s lettered correctly with Shell on one side and BP on the other and is known as the type one livery which lasted until the late 1950s.

You didn't step on any mines that I'm aware of.:)

 

I've seen a photo, dated 1954, of a string of three "Airfix" 20t Shell tanks that appear to be in buff finish. My Airfix models have Shell branding on both sides. Is that OK for the livery post-war or should they have BP on one side?

Does anyone know the background to the Carless Petrol example? I cannot find anything about a number 10 example in my books :(

 

Specifically No10 or Carless in general?

I wonder if these examples were dedicated to a special traffic? As has been pointed out, Shell and BP pooled their fuel tankers, which carried both companies' logos. However some tanks were not included in this arrangement; the most obvious examples being the ones that ran between Pumphurston and Grain on shale oil and paraffin wax traffic.

By 'Airfix' tank wagons, do you refer to the RTR or kits models?

& Mobil  (Charringtons)

 

& BR

 

 

But didn't Esso have the first ones?

 

Also, the Airfix kit only came with Esso transfers, though I understand others have become available since Dapol took it over.

  The three prototypes were branded  Esso. There was also one for BR. The are books and a good many articles that have been published down the years giving chapter & verse on the 35t GLW tanks and models of them.
