I haven't dealt with any safes but I'm wondering why you need serial numbers for your? sentry safe? Also, I'm not sure if your asking if you have a 7 or 8 pin tubular lock. If you have the lock YOU should be able to tell if it's a 7 or 8 just by looking at the key. You do have the key don't you? If not, just count the pins inside the lock.
