I don't know if the market's softened on standard bolt face stainless LH M70s. They just don't show up very often. The last one I saw on Gunbroker went for over $2K in December. Unfortunately as Snowwolfe said, you generally don't get your money back for custom work, and in some cases reduce the value from OEM. I would agree with the others of how to get the most for it. Given the nature of auctions, the results might surprise everyone, high or low.
