Jerry,
28” twist makes it a pretty scarce gun, and it sounds like you’ve got her shack’n up with some pretty good company!
Destry’s right, if it weren’t for the Southern and a couple of other multi-gauge competitions, I’d only ever shoot maybe one 12 ga hammerless, one 12 gauge hammer gun, and one 20 gauge for the doves and my new found fun, quail!

The Parker hammer will be restored to match..I'll be the first to admit that I usually get carried away with these projects !.....After that is an English J.W. Laird top lever 20 hammer.. Bores are iffy..so may be a tubed 28 ..
