Bruce, that is an interesting question and it reinforces the fact that if we ever have a "Parkers For Sale" page on our website it should be limited to the seller's post - in other words, he owns the thread and nobody else can make comments about the gun, either pro or con, thus, eliminating any opinion - expert or otherwise.
Mr. Lien's comments and expression of his opinion certainly serves to raise awareness that we must all be ever watchful of the possibility of upgrades, alterations, refinishes, reconditioned guns and that there are people out there who can sometimes deceive even the most serious collectors . . . so, let's be careful out there gentlemen.
Beyond this . . .
