Well, thank you very much.
I've been checking around for the OOP Mills and Barnes book, Amateur Gunsmithing, for a while. Usually not available or costs more than $250. Just ordered for $61. + shipping. Once I searched by ISBN I got a bunch of listings.
BIG AL,
The Addall search included Abes. Abebooks was who I used, and they were sourcing from an outfit in the UK.
Yes I know they source through all including Abe. Addall was given to me by a book dealer friend of mine and I have yet to find the same book listed by addall that was not higher than the same book when you find it on Abe. I have for many years had to keep an annual book buying budget, so I have found that I have to price shop more than I would like to do.
