Your lock is very similar in design to our 38-144. I think this may be just what you need but look it over and let me know if you agree!

thank you. I will measure. Will we also need the counterpart to this lock?

The new lock should be compatible with your old keeper, but it can't hurt to check. The keepers designed to go with the 38-144 are the 38-276 and 38-277. You can give your old keeper a once-over just to be sure that they're the same.
