I just looked at ours and it has the same CH 751 in a circle that is raised. On the other side it says Wartian Lock Co If you PM me with your phone # we can talk. I can get another made, but our trailer is on Ebay and the auction ends tomorrow Monday July 26th in the afternoon and we have several who maybe lined up to buy.
