Barrel flat - frame size stamps
In order to determine if a barrel will fit a particular frame size, is that a series of measurements taken and/or a stamping on the flats that corresponds to what frame size it will mate with?
Thank you. |
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 |

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? |
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.

Barrels will be marked with the frame size on the bottom of the bolting lug. With the exception of very early hammer guns and barrels that may have had their stamping filed off for some reason.
Determining frame size of the frame itself would require measuring certain areas of the frame. Firstly the firing pin spacing. And for some frame sizes, the height of the standing breech is also an important area to look at. |

Thank you. |
TPS page 527? has a chart with all the measurements.
|
What bill said. The serialization book also has this info as well.
|
Thanks. I have neither book. I guess I'll look around for copies to buy.

http://www.bluebookofgunvalues.com/P...tail.aspx?id=7 The Parker Story is a two volume set that has a tremendous wealth of knowledge Check with Double Gun Journal to see if they still have "blems" - you won't find the blemish and it's a great price |
Thanks. Doublegun lists blemished two volume sets for $295. Can't swing that anytime soon, but I can manage the serialization book. Thanks. Now I just need a barrel. There's one online that looks like it would work, but there are no measurements listed to determine if it's a viable option. The only markings cited are:
"marked Parker Bro Makers Meriden, Conn. Damascus Steel. It is pat Apr 11, 1876. It is 12 gauge with 30 inch barrels. It is also marked D5 with a little 10 above. Original note in left barrel states serial number 58464." |
The 5 and offset 10 is the unstruck barrel weight 5lbs 10oz
|
You're going to have to send us a bunch of pictures to solve the mystery of small frames with big barrel weight. We doubt that you have a #1 or #1 1/2 frame gun. In the place of pictures, you could send us measurements.

I think he is looking at one for sale, not one he has in hand
if it's the one I know of. The seller says he cannot find the frame size marked |
Bill watch Ebay for copies of both books. Sometimes used copies come up for sale at a good price. Some sellers want as much or more as you can buy the blems for.
Also check out boxes of gun books at auctions for these as well. Do you have the original barrels for your gun to take measurements from? erick |

In searching for a replacement barrel I found one that had no frame size marking, but the struck weight above. I'll measure the distance between the pins tonight. |

What rib marking is on the 5-10 barrels? Specifically, the type of steel.
|
Damascus Steel as noted in an earlier post he made.

bill those barrels on ebay are probably 10 ga barrels...the barrels would be pretty heavy for a 12 ga unless they are 3 frame 12 ga barrels...i expext them to be 10 ga..i have bought a coupla guns expecting them to be 12 ga as listed in the sell ad and they where 10 ga but was happy with them being 10 ga....charlie
