POHO-- I think you mean 1919 not 2019! There is actually a nice video of the M1917 production at Eddystone posted on You Tube. The video is erroneously posted as being of the Winchester plant which it is not.
I have attached the only surviving building of the Eddystone Rifle plant. It was used as the Woodworking shop for stocks and handguards. After the building was turned back over to Baldwin Locomotive it was converted to a steam plant. The Cross shaped building in the background was the company headquarters for Baldwin. It looks more like a correctional facility then a headquarters.
