410 O Frame?

Mark, an 0 frame Breech face is 1/8" wider than a 00 frame.

I am pretty sure that the OP is looking at the .410 stock that is for sale on the internet and advertised as an 0. But it is more than likely an 00 frame. The seller should be asked for measurements of the head in order to confirm.
Since an 0 frame .410 would be a very odd duck, if not a non-existent duck.

1 5/8ths”

So O, OO, or OOO?

A few examples. Note the screw in 227044 used to hold the grip cap on grade 5 and higher guns.

Thanks for the answer...and, especially, the pictures.

I have the stock that you are referring to. It measures a hair under 1 5/8 or a hair over 1 9/16 at the head.
Serial number 233299
I can't access jpg to add a photo at this time.

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.
