The bathroom was probably installed in the 1950's. The manufacturer name on the hinges is Mills. I checked the door hardware in another bathroom in the church, however, I was unable to see any manufacturer markings on the latches or strike/keepers.
There are holes where the previous hardware was attached (no one knows what happened to it!) and the goal is to use those holes and not drill any more if we don't have to.
Door: hollow metal, 1" thick, rounded edge, inswing
Two holes for latch: 1/4" holes, 1-7/8" apart center to center, set back 1-3/4" from door edge to center of hole
Pilaster: hollow metal, 1-1/4" thick, rounded edge
Two holes for keeper: 1/4" holes, 1-5/8" apart center to center, set back 1-1/4" from pilaster edge to center of hole
The horizontal measurement from the latch holes to the keeper holes is 3 1/8" center to center, allowing 1/8" for spacing and for the rounded edge on the door and the pilaster.
I have attached photos from a stall with all the hardware and the exact same measurements for the parts I need to buy: 1 latch with 2 fasteners and 1 strike & keeper with 2 fasteners (one strike/keeper, or 1 strike and 1 keeper as separate parts). The hardware in my photos appears to be stainless steel with Phillips-head mated fasteners.
