You can end-run GB's garbage fees by posting a picture with your letterhead or business card etc. along with all the gun pix. People will contact you directly to ask what you really will sell it for. Be prepared to offer them a significant reduction. That's how I got my Lanchester for $1K less than the seller's asking price on GB, basically he sold it for what he would have gotten at his ask minus their fees.
Everyone seems to be out of stock at the moment but you can get notified when available

I had seen the one for $250 and decided that I didn't want it quite that much. Somehow I missed the one for $10 but I just bought it. Thanks for the heads up
Numrich catalogues this manual but shows it as out of stock. I seriously doubt that they will be restocking it anytime soon. If anyone has one they'd be willing to sell I am interested

Don't know if this has been posted previously on here of not. The site looks legitimate but they have been reported as a scam on several other web sites.

Their prices seem WAY too good to be true so caveat emptor. If you're feeling adventurous here's a link
