I didn't think you were dumb before. Sometimes as it would seem we know what they are but don't or aren't using the same terminology. That makes it kind of difficult some times.

I've been told that French guns for some reason seem to be proofed to the heaviest load possible a lot of times. I have a 2 1/2" 12 gauge french gun that shows the triple marks. The gun was purposely chambered for the 2 1/2" load and was manufactured in the late forties. Unfortuantely the barrels were sawed off at about 18 1/2 inches by someone. The stock was also cut off a bit. Thus it will be a future conversion.

As far as your. Sorry can't help.
