Hi Mr. Z! To reiterate that I do bow to your gunsmithing expertise. But here's my eval. The O/P comes to this Forum, seeking item "valuation. He describes and moreover purports certain alterations done to his satisfaction. Presumably his inferences: 1. that in his judgment they're properly accomplished. 2. that he is satisfied with the situation such features reflect and 3. that they ostensibly add value. Fine! To accept all these statements as absolutely true. But the "valuation" he seeks is to the gun buying public. The fact of what he subjectively considers adequate and 'value added' is irrelevant. For public-objective valuation, necessary to view and assess such employing objective expertise. I've seen some abominations which were proudly displayed by owners! The other element as my harping, in this Thread. The multi-unknowns concerning this gun! This is NOT a question arising of battling expert evaluations! My core argument, there is simply too little objective information offered by the O/P to make any kind of reasonable valuation assessment.
I do agree that sometimes there is a 'floor' value possible, predicated upon such as components and accessories which themselves suggest value. No argument there. Yet question of their proper fitment & condition? A seller can be and should be expected to provide some minimal amount of objective information! Where such is lacking, the red flag syndrome!
Well over a half century of gun collecting, I've viewed, discussed, researched, examined and owned a substantial variety of mausers military and commercial. The proliferation of models, the variables of condition, the pushing full century some in existence; all create the potential and lean toward natural deterioration and hand of Bubba!
The bottom line not a question of battling expertise but of sufficient 'objective information' for experts to employ their skills. The person seeking valuation(s) cannot foreclose areas of inspection by dismissing in context of "satisfies me"!
Another 'my take' if admittedly 'wordy'!
Best!
John
