If someone represents themselves as a "Luger Collector", it's reasonable to assume that they have the ability to disassemble field strip a Luger. To the extent possible, if I were selling a matching Luger, and a serious buyer was ready to make an offer that I would accept, I would be happy to sit down, take out a mat and show the buyer the matching parts I could access.

If a seller was unwilling to do that, I would simply offer them a price for the pistol as a "shooter", and tell them that if they wanted anywhere near to a "collectible Luger" price, I need to see the matching numbers and condition of internal parts.

if you are inexperienced at disassembling firearms, never ask a seller to let you take them apart.
