The first suggestion of an anchor was in post 2 of this thread!
I say that the mark means a lot. I'll share a tale of three mindblowing revolvers and how it occurs to me.
All three are purpose built PPC competition guns that were likely worked on at some point between late 70's and mid-80's. First one is a 1956 S&W pre-Model 10, it looks exactly like every other blued PPC rig from that period, it's customizer is unknown and he left absolutely no mark unless it is under the side plate that I have not removed.
Gun #2 was born a stainless Ruger Police Service Six, but the shop of the legendary Bill Davis installed a 6-inch stainless Python barrel, a Millett adjustable rear sight and a completely inspired trigger job that would make any Ruger fan cry. Davis marked the frame with a very catchy and prominently placed logo and the fact that the revolver has YEARS of obvious heavy competition use is the likely reason that I found it so affordable.
Gun #3 was also fully customized for PPC by a true legend. It's a mid 1960's Model 10 (going from memory if I am not mistaken) and every single detail of the work matches right down to the exact minute detail of what Travis Strahan did to PPC revolvers. Except... Strahan did not sign the right side of the barrel at the muzzle as was his custom.
All three spur my emotion. The first revolver is the finest of the three and while it will NEVER have the "value" or marketability of a Colt Python, the double action trigger stroke would ANGER anyone who ever spent (2018) Python money to get the Python trigger. Whatever your guess is about how it might feel, it's better. And yes, only Federal small pistol primers need apply.
Gun #2 is interesting, a cool sign of the times and pure pleasure to shoot. The Davis logo is the cherry on top and I love it.
Gun #3 has an aura because it is the work of a legend that our hobby was blessed with, but it frustrates me that I don't get to see his electro-pencil signature. I can only imagine that the original owner requested it be left off.
My position on this subject is obvious but what may be a little more obvious now is that it isn't a knee-jerk response, I have a lot of thought in to the question.
When you order a Lone Wolf replacement Glock barrel, it arrives with a Wolf logo that looks like a canine with a methamphetamine problem. For an extra $20, you can get it without the frothing cartoon wolf. If I had a 3rd Gen that was transformed by the BMCM shop, I would ask for a slick and classy logo added to the work, but I would want it somewhere that I could see it without removing anything including the slide or grip(s).
