Hey, I let him name his price, not me. Didn't even dicker with him. What really surprised me was that a dozen guys looked at it before me, and didn't buy it? It did look pretty crusty, and the bore hadn't been cleaned in years, but I figured the action was worth the $100. It wasn't until I soaked it, and cleaned it, that I found out what a decent gun lay hidden underneath all that crud. Several guys who saw it cleaned up, regretted not taking a chance on it before me! Their loss!
The forearm has one screw, as do all Remingtons also. I have two other rollers, and a Hepburn. They all use a single screw to hold the forearm, on sporting type rifles.
I'd like to see your buffalo gun when you finish it! I saw an original Remington heavy octagon barrel, with a new Rebmans .45-70 liner for sale at our show this last weekend. The guy wanted $125, and it would have screwed right on the Whitney, but I hate to change the Whitney after it came out so clean. I sure contemplated it though!
