Go ahead, miniaturize me too...I'd be happy to work there.
I noticed only one possible error - the Foreman's desk had Colonial Revival hardware, whereas it would have likely or certain to be Victorian 1840's - 1901 and beyond.
I'm not aware what function the loose fitting rings on the lineshafts performed. First reaction; sort of a visual indication it is running? Here is proof that model-making can mean miniature, real and functioning; where miniature doesn't necessarily indicate the same things.
