Well I went back and took a 2nd look. G grade, chambers are indeed 2 7/8".
The dealer who had it had several tables of synthetic stocked rifles and pistols. This was hiding in the middle of a rack of rifles
I explained the "difficulties" this old gun has such as short obsolete chambers, Damascus barrels and looseness in the lock up.
Walked out with it for $100
