This reminds me of the service you get from Dillon Precision. Dillon warrantees their mechanical products (presses, scales) for life. Not just to the original owner. If you break it they fix it, free. If you find an old beat up Dillon press, send it in to them and they will make it good as new, ship it back to you all at no charge. They get all the business I can give them.

I will look into Copper John for my next sight.
