When I was first getting into this stuff we were hearing all the time about having to get Parker Bros. 28-gauges rechambered because the rim cuts wouldn't handle modern ammunition. Between that and the changing shell lengths for 28-gauge ammunition, I suspect that by now, very few 28-gauge Parker chambers are the way they originally left Meriden.

Dave you are spot on.

I have no idea how owners of early 28 gauges approached the rim cutting problem. I was lucky in that, as a teenager, I was employed in a very well equipped instrument shop and I set up the rim cut on a Bridgeport vertical mill with the help of my talented employer. When I obtained #97032 a few year ago, it was easier. I borrowed a 28 gauge Manson rim cutter from one of our members.
