David,

I’m finding that to be true. I’ve poked through several threads and posts including some very helpful ones from Pete but believe the series goes up to 36. I have not found any of the Q series ward/lever cuts diagrams.

I’ve managed to track down keys for the 18 P series Corbin locks in my house but this one Q lock is providing quite the challenge.

Good news is all of the door hardware including locks has been cleaned of 90 years of paint and re-installed on stripped/painted doors. Now that we have doors everywhere again, Mrs. PC is happy and I can take my time finding this last treasure.

Thanks

PC
