I have 8 or 10 really big combo SAE wrenches, USA-made, mixed brands (Cornwell, SK, etc). They are very functional, but several of them are rusty. I had planned to de-rust them and get a friend of mine to cad plate them. But I have a MILLION projects. If you are interested in these rusty giants, I will send you a list, photos, and a price plus shipping. (Maybe about 50 bucks, plus shipping)
Does this interest you at all ?
