Hi guys,
where could I find good information and pictures of Prewar layouts and construction methods for tunnels, etc.? Most of my trains are from 1912-1942 (with some newer and modern production) and I would like to make a layout more or less "Prewar-themed". Considering original Papier-Mâché tunnels seem to be difficult to obtain, I would prefer to make my own if possible.
Thanks,
Alex
