Been working (fighting actually) with this bore scope for the past couple days and finally got some pictures that are kind of presentable. The Belgium made set has pits ranging from moderate to severe:
In the left bore, this is 13 1/4" inches up from the breech. They appear to be moderate and given the wall thickness at this point should pose no problem. The largest part can be cleaned up with the hone. From the right bore:
This is 6" up from the breech and a bit more severe than the left. Trying to completely remove the worst of it could make the barrel wall too thin. Since this falls within the "high pressure zone" we'll hit this area with the hone to clean it up as much as possible and let it go it that. It may or may not cause problems with the shot pattern.
The unmarked set has nearly pristine bores with extremely mild pits just ahead of the forcing cone in both barrels. They show signs of considerable use but the previous owner(s) obviously took very good care of these barrels. Next we'll fit both barrel sets with breech plugs and proof test them. Both should proof in fine order.
