Value detractors

[Edward Tinker]

Again, as said above - comparing the ones you compare, they are totally different -

I HAVE found that import marked guns seem to have taken on an almost accepted status compared to say 10 yrs ago. I think its because of the Sturgess collection that came in with hundreds (many hundreds) of import marked lugers and literally over a thousand guns, and the import marking by Simpson was small on the butt of the gun (now moved to near the trigger-guard).

To most collectors, an import marking, mismatched (not counting mag, that is considered expected) or even a professional refinished gun are deal killers. They just are.
I have owned all of the above, but given a choice in the below, I would still take a 80% gun compared to any of the below.

Refinished - its lost its history, would take a 80% matching (not mag)
Mismatched - depends on what is mismatched, firing pin or grips would not put it into a 'shooter category to me
- but lets say the takedown or sideplate is mismatched, I would take a 80% gun over it.
Import marked gun - I would take an 80% over it

HOWEVER, as said above, for a rare model, I would take any of the above, but consider it a placeholder until I got a better one.

PS: I have bought several mismatched guns, hoping to find a part (sideplate or takedown lever) - it is very hard to do, you'd think it isn't, but it is.
