Its been an interesting discussion.
I can assure everyone here that the real motive of the aforementioned (and beaten to death) supper meeting was to fill our stomachs. Or at least that was the primary reason. And David left out my wife as one of those present. Her entire motive was a nice supper!
People opinions change when they handle a gun and can really inspect it. At that point in time I had no question about the lack of orinality of one of them. It was clearly a good refinish, and it isn't part of this discussion (but it is a part of a different, email discussion.)
Whenever you hand a gun to other people, collectors, experienced shooters, whatever, you need to be careful not to poison the discussion. Some very honest but well meaning people will tell you what they think you want to hear, or hedge if it runs counter to your beliefs. Thats why you don't tell them what you think till they've told you.
We spend way too much time and effort preaching what the factory did or didn't do. We just don't have all the answers. When you have the gun in hand, and a magnifier, and good light, you just get an opinion or idea. When you get candid opinions from others, and everyone that handles a gun agrees, its a strong trend.
I believe at the time David, Jim, Lee and I all came to the same conclusions.
The rounded and flush pin question came up here on the forum about 5 years ago, in the context of K32s. That was when I had a small accumulation of them, and I had both posibilities on several guns. That was back when I was posting photos, and there was just no question that in the early postwar years they didn't follow any rule. What suprised me a little was that early ones were both ways, as were later ones. That told me that there wasn't a preferred method, or at least to the exclusion of the other. Probably depended on who was doing the work.
