Here are the pictures you requested of the lock, we are trying to get a replacement of this part that contains the deadbolt as well.
Thanks!
(When 40-194 and 40-198 were suggested.) Either one of those would work but unfortunately the mortise measure 1 9/16 part is the only measurement that doesn't fit. Do you have any other ones with all of the same measurements except 1 6/16 mortise?
Thankyou!

Attaching the measurement, measured again it's defintely 1 6/16 (3/8)
