I sent a message a few weeks back but received only one response - so here
goes again.  I am looking for any information you may have on the history of
museum models (working coal mines etc...the type you press a button and it
springs into action) and or dioramas - I have a brochure from the late 1920s
that advertises a company that made models and I am trying to put it in context.

Anyhelp, leads, ideas would be most gratefully received.

Thanks
