Sorry for being late with response. I took photos this Am left film with nice lady that develops them for me, then went rabbit hunting. We have a good supply of jack rabbits again.
The barrels came off from a DHE Parker that was from your neighborhood. They fit the gun without a lot of work. I took the barrels to the Vegas Gun Show twice and asked the east coast guys who they thought was responsibly for them. many said that they thought DelGrego, and or Frank Lefever, some said maybe a joint effort. Time line was late 50s early 60s???. Their story… MAYBE OUR MAN BILL MURPH WILL GIVE US HIS OPINION... . We could most likely bet a beer on what he says..I think that I have three or four good photos here.
The rib on these barrels tapers from .525 little over 1/2 In. to .280 just over 1/4 In. It is a REAL DELIGHT to look down them at a late season Pheasant with both barrels loaded with a good stiff load of hard lead #3s. The barrels shoot 60X40 and to the point of aim. The .030 chokes likes big shot and pattern well.
