Mechanically clutched, flywheel driven, straight side punch press.
Unsure operation going on, a lot of daylight between punch holder and bolster, but there is something on the left side. Looks like a cart of tools, not parts. Without feed reels, might be trimming or other secondary operations. It's a good picture at regular size, fantastic enlarged.
A surprisingly small power hacksaw is behind him, and varied bench machinery along the wall.
