Please Show Me Your Door Latches

[Tony Caldwell]

I'm having difficulty figuring out how to repair the door latch on my 35-70.  I'm curious to see photos of the different kinds of latches Porterfield used to see if I can figure out how to source a replacement.  My mechanism is about 37/8's square and an inch thick.  I thought it was an auto component but now don't think so.  I've looked at drawings Tom sent but they aren't anything like I have. Thanks.
