Many thanks to Raymond for his help tracking down the code information I was looking for. Blanks for this lock came in yesterday, and I was able to cut a working key with the information he provided after work. Based on the info provided it appears this lock is significantly older than I thought, so I ended up having to cut the key about .003" higher than spec and about .005" closer to the shoulder to compensate for wear on the pins and the face, but with that it's working extremely smooth. It's wonderful to be able to breathe some new life into an old lock.
