Layout is a 1939 Multiplex "modular" ... simply put the sections of track together .... Multiplex did sell generic sections of track .... but this was a planned layout ...won 2nd place in the MC layout contest 1942
I was oh so lucky to be able to purchase the layout ... unfortunately 4 sections were missing ...so I did some cheating ...to make it work again ...still need lots of scenery and fine tuning
Cheers Carey
