The factory in the picture dates way back to my HO model railroad layout days from the '70's. It was a hobby I shared with my dad and we would spend weekends assembling the various buildings together - my dad really liked to work on models! This factory is the AHM Gruesome Casket Factory. The fire station in the picture with the Hongwell VW is an old Plasticville O/S scale snap assembly kit. I bought it, probably in the '80's to use on my 1/64th farm diorama when I used to do the farm toy scene.Are these assembled by yourself?
