The flooring went a few years back apparently which is a shame.
Yeah that is the kind of type which would have been installed in the building .W3ell 2 of them as it is a 2 bay link trainer building.
That type shown in the picture above is early type as it has the zip compartment sides when the next 40,s version was a sliding door.
I currently have a c3 version in my workshop which i am rebuilding to running condition .Another few weeks and she should be up and running.Great pieces of kit to work on and pretty complicated for the 1940,s.
Mine is about 1943.
