One thing for sure is that there were lots of changes and variations in the 1 and 1 1/2 grade guns.
Specifically with the 16's and 20's, I've seen most every combination of engraving and tube steel in those grades.
Plenty of the guns lack a grade stamp of any kind.
Krupp barrels being seen often, chain barrels several times.
Unfortunately, I didn't record all of the serial numbers.
Some of the Krupp barrels are marked on top, some only on the bottom, some both.
Some of the guns marked on the underside only may have even been field grades.
Bill, I believe that your gun may have been in a serial block run of 30" Krupp barreled 16's.
I want to say that it was like 100-150 guns.
Perhaps Walt can verify that or at least where that block occurred.
