Put the number in lost and found and see if something pops up.

Likely got rebarreled due to one of two reasons. Damaged/lost original barrels. Or Damascus barreld that were "unsafe" to shoot.

Brian, I have measured these Q1/Q2 barrel chokes with a brass Galazan gauge and both barrels measure out cyl and cyl. Does this seem an accurate measurement (or as I suspect) the Galazan gauge may not be the most accurate one in the tool box. How should Q!/Q2 chokes measure out?

Galazans drop in gauge is a quick check type of tool. And it will only be reliable if the bore diameter is a true .729" or close at least.

The report barrels would be, but the difference between Q1 and Q2 are pretty minor. Kind of like SK1 and SK2. Without a dial gauge, you would not know the actual constriction.

Unless they have been altered.

Thanks Brian. I measured them again and with my cheater glasses on I can see a very slight difference. Don't think they've been altered.
