I know what you mean, Joss. The only reasons that I can figure are that either they love to wrangle, or they might be a day or so overdue for their reality check. Some of 'em seem to carry the ol' "ask more than you expect" axiom a tad far, IMO. Can't blame 'em much for wanting to get the most they can on the deal, but those "Values" books ain't the Bible. Like my ol' Grandaddy told me, "The only reall worth of anything is what someone will pay you for it on any given day."
St. George: From the look of the firing pin bushing and surrounding breech face, I don't believe that it's been fired since it was proved. Certainly I haven't done so, though I've been sorely tempted to on more than one occasion. I do have to admit that I have cocked it and tried the trigger a time or two. Still, the "ring" is so slight that no blue is missing anywhere and you have to get the light just right to see it. With a difference of $900, looks like "when" and "where" are both worth about $450 come bettin' time. Makes me wish I was a better poker player for those stakes, that's for dang sure!
Two Flints: I'll check out the rules here and on other sites before I post it anywhere. I know that some venues insist on exclusivity for at least a period of time. While it's in my best interest, as I see it, to try and reach the largest number of potential buyers possible, I don't want to violate any user agreements in the process. The "brick & mortar" guys get an exception, but they pay the site for it. I can well understand why the moderators would want to avoid the headaches of mediating foorahs amongst their subscribers because somebody feels "cheated" when told it's already been sold and the fact wasn't evident in the thread. Especially when they're offering the service as a courtesy and aren't making a penny on the deal. More potential for bad Karma, I don't need.
Vigrinia Gent: My guess is that the chambering was dictacted by "authenticity" and congruence with original production models. Something to do with the parsing of "re-production" and "reproduction", no doubt. Aesthetics aside, I can think of at least a couple of practical reasons why they might choose to go with the change to a frame-mounted FP, but I'd bet my second-best Bowie that the corporate lawyers' liability concerns had more to do with it.
