So the last bit was cap for the post. The bits I found in the signals odd-and-ends bag turned out to not be what was desired. However, further rooting around produced a brass disc (I'm guessing a counter-balance weight) that was only slightly oversize. Filing this to fit, it needs to be a kind of dome affair going by the drawing, was not going to be easy. Then the little grey cells had a conference and Plan B arrived... I soldered it to a off-cut of the correct size post, then it was easy to file it to the desired size and shape and glue it to the post.

Everything then got final coats of paint - and it's done. When the paint is dry off comes the tape on the post, two bits of white splash to cover with black and then off to eBay.

It's been fun, if a little slow due to making it up as I go along. The first one I built , for my layout, didn't take long to build but is non-working, it's lit but no operating rod for the signal. Making this a working one has been something of a learning curve, as indeed has been finding out about the variations of the prototype. Every day's a school day :-)

Now to clear the decks for the Parkside SR 20T Brake Van. I may use this as the prototype for roller bearing wheels if they are available, another little project I fancy trying.

Happy New Year, lets hope it works out better. I'm not risking saying it couldn't get any worse.
