I work for an Ironmongery company and we have never seen this type of handle and latch before. This must be a very old style handle. Do you need exact replacements or are you happy to find something a little different?
Hey There! I may be too late but I just wanted to let you know that unfortunately these types of locks have now been discontinued. I am not sure of anywhere were you would be able to pick one up. Latches do not come with a thumbturn option anymore, instead you would have to get a latch with handles ...
