Hey KyJames, IF....you decided to shoot that original, Lodgewood.com has a repro cylinder for originals for $105.00, and they are IN STOCK!. I have purchased from them before and they are good folks. I bought a new repro cylinder for an original '58 Remington a few years ago, as well as other items. They have repro nipples for originals too (original thread size). I don't know about hole size, but a call to them would probably be in order.
