Barrel flat - frame size stamps

[OH Osthaus]

The rear most barrel lug should be stamped with the frame size

To determine the action frame size you need to measure the distance between the center of the firing pin holes

Sorry. Yes. I got it backwards, and should have written water table instead.

I've been searching for a barrel for a 1 1/2, and have found a couple of barrels but there are no lug markings to denote the size they'd mate with. Did Parker always mark the lugs with the frame size the barrel would fit?

[OH Osthaus]

Well. I have one that is not marked

You seem to have seen a couple

So I'd say. No not always

Put fired shells in the chambers and measure to the center of the primers. This is the "non machinist's" method of measuring firing pin distance by just using the barrels. 1 1/2 and 2 frame firing pin separations are the same, but other measurements are different. Refer to The Parker Story, page 527, if I remember correctly.
