A few weeks ago, I mentioned that Brummie buses didn't stop at shelters looking much like the Merit concrete version. Birmingham had it's own spindly metal design, which appeared all over the city.
As far as I know, none still exist in the real world, and I'm not going to tour the bus routes to find out, but Wythall transport museum does have one, and I've taken some photo and measurements.
A few detail views too, in case I want to try and make one.
The shelter seems to be a mix of steel and fibreglass - for the roof panels. It would have been a revolutionary material when these things were built!
For modelling purposes, I can only think of etching. There's no other way to achieve the strength for a model that will survive, and delicacy of the window bars etc. Maybe you could cut it by hand, but I doubt the result would be particularly neat.
The measurements for one bay (the stop photographed has two) are below in scruffy notebook form:
I'm not planning to build one at the moment, but it's useful to have the information - and this post might help someone else!
