I hope to be replacing a 35 Rem barrel with a longer one from a contoured blank. I've looked everywhere (including Speerchuckers many) and found general tenon diameter and length specs but nothing about the hood or extractor. I know I can measure the old one but would also like to have a reference. Thanks

I just copy the old ones. Very simple. Never saw a drawing and even if I had one, I wouldn't use it because it would be sloppy like factory barrels; I tend to fit barrels better than factories do.
