Reading from left to right I would like to know what the last marks on the barrel are called or what they signify. I have a shotgun that I can't ID with a similar mark.

Pictures of the gun were posted here some time ago and we were never able to ID the gun. Maybe knowing what the mark means will help. Dealers have looked at the gun--some think it is English others German--no on knows for sure.

I can't post pictures--too dumb. Daryl Halquist did it for me earlier.
