Help identifying replacement locking handle in black.

The photos of installed handle are on a door that slides right and removed handle is from a door that slides left. There are no markings whatsoever on this handle but there is a sticker on the frame that says 2014. These were a gawdy gold and I spray painted them black but I'd like to find one of each in black as the paint is beginning to rub off on one. The mounting hole space is 3 5/16 and the door is 1 1/2" thick. One photo shows length of the handle.
