Hello Hugh,
If I were in your shoes, I think I would put the 100% magazine safety into a police luger of my choice and then represent it, to a future buyer, as a historically correct, original replacement part.
I think I could sleep well with that...
p.s. Another option; put that little piece of metal on auction with a opening bid of $ 450.00 and see what happens...I think these are rare at 100% intact, so you might be surprised what some folks would pay for one...
Regards,
Pete... <img src="graemlins/yltype.gif" border="0" alt="[typing]" />
