Replacement mortise lock

Question

I am looking for a mortice lock with Patent numbers 6.626.252 and 5.820.170 and a date of JAN 12 on the side of the lock on the opposite side of the patent numbers. We found a MAR 20 version but it appears the design has changed slightly from the JAN 12 version. Do you have the JAN 12 item?

Thank you.

I'm afraid I don't know the distinction between those two dates. That's never been a relevant detail in my experience. Looking at your photo, your mortise appears identical to our 82-260. If there is any difference between our product and your old mortise, I can't see it. What changes did you note, exactly?
