Thanks for the comments guys. I've been happily suprised by collectors and I've engraved quite a few rare planes for folks all over the world. The rule of fine engraving is, like the hypocrtic oath. First do no harm. In any engraving , the finished piece should be worth more than what the tool or gun was worth as it sat, by the value of the engraving applied. I do know that my work has risen in value over the last year as collectors have been willing to pay more for the work. I let the market dictate. It is definately an investment.
