High-quality black-and-white photographs of large old machines and tools

[marksbug]

some of these pictures make it look like a small machine....very small machine, with big handles & knobs. just think of all the parts to a train and them each being made in batches and then assembled...lots of very heavy parts. and presision made...or else if the wheels were off in dia it would just go in circles like nascar. now wouldent that be a sight. nastrain.
