410 O Frame?

[Dean Romig]

Mark..... the only correct way to determine frame size is the exact distance between firing pin holes, center to center.

1-5/8” is off the charts. A 7-frame is 1-7/16”

But I think your measurement is the width of the stock head. But this is not the way to determine frame size.

I think I just misstated what I am trying to discover. Based upon the chart attached from the serialization book, it would appear, that all other things being equal, the head of stocks from O,OO, and 1/2 frame guns would, should be interchangeable.

Dean, we have discussed this over and over, both on the phone and here. You know the center to center dimension of the early SMALL framed hammer 20s was 29/32", 1/32" smaller than the finally adopted 00 frame, or 1/64" Difference between the actual firing pin of a true 00 framed gun, and the center of the chamber of the early SMALL frame 20s. However, what matters equally is that the width across the bolsters is the same, as is the height of the breech face, from water table to top of bolster.

I typed SMALL all in capitols, because the first several 20 gauge guns were a mix of 1 frame, and the frame eventually adopted as 00 in hammerless guns.
In making many of these early 20ga. guns with such a small frame, Parker Brothers must have had a very good reason, however, it's anyone's guess what it was.

Right Mark. 1 5/8" = 1.625"

I have a 16 gauge on the 0-frame that measures exactly 1.641" so, they're not exact apparently.

It does not appear to me that the width of the action (wood) is mentioned in the chart. The wood may be 1 5/8" on the three smaller sizes, but the chart doesn't show it. Dean, no, the 00 frame .410 Scott and I discussed is not a prototype, nor do I believe it is unique. I just know I would like to own it, and will know it when I see it.
