This is an early American bronze commercial style door handle that is in Edwardian style with 3 pieces, the upper part has the thumb activated release. I do not have the latch for this. I remember these on upscale commercial properties such as hotel lobbies, bars typically using double doors. This is as found, unrestored, has some reddish paint overspray on it in the upper right. this is unmarked and the maker is unknown. great for repurpose. What you see is what you get.
