This is one I got yesterday after a 3 hour drive each way to see it. It's a BW (Barry) Darr barreled Rolling Block, chambered in .35-40, which is a blown out .32-40 case. It is a very heavy 4.5 weight full octagon barrel that's 30" long. Also came with a Darr mold built for this rifle barrel. The barrel is marked "BW DARR" on top, and under the forearm is the barrel number, .35-40, 12-10-75, and 1:16 Twist.
Forearm is a bit too bulbous for my taste, so it will get lightened and slimmed down. Probably remove the barrel and wood, and get the receiver color cased also to make it look better.
Been trying to buy this rifle for almost 4 years, so it was worth the long drive. I also ended up buying a couple Ballard rifles he had, and put my name on a 1874 Sharps Gemmer rifle in .50-140 too. A huge bunch of Ballard stocks, and parts, and some neat re-decapping tools he wanted to move along also. Tools are some Simmons, a Pope, a Schoyen copy, and an oddball I'm unsure of?
Bought three barrels for Ballard rifles too. Two are factory barrels in .22 Long, and .40-63. The 3rd is a George C Schoyen barrel in .40-50SS, and still has Schoen's traditional brown finish on the heavy 30" full round barrel.
