Frame Size

[John Davis]

I guess I never gave it much thought but the records for SC's 237938 and 237939, both 1935 Remington era guns, reflect that these two SBT's were built on 1 1/2 frames. The barrels on 237938 are not stamped with a frame size, nor are any of my other Parker SBT's. I didn't realize that the Parker single barrel trap guns were made on different frame sizes. Or were they all 1 1/2 frames?

Would you assume the few 20 gauge singles were on ever so slightly smaller frames ?

1 frame maybe?

[Dean Romig]

How does one determine frame size on a SBT? I have never seen anything published that alludes to frame sizes. Further, it makes no sense whatever to presume Parker would have produced a different frame size for the five 20 gauge SBTs made.

Sense or not I’ll not argue that point . However I think you’ve heard the old saying “never say never” when it pertains to this type thing . I wasn’t saying it necissarily was just did anyone know for sure they’re the same size 12-20 that is .

I was wondering the same thing. And that reference in the stock book is the only reference I’ve ever seen.

[Dean Romig]

Right Craig. There are frame dimensions published for each framevsize but thise are for sxs Parkers. I’ve seen no such dimensions published for the SBT Parkers.

Cant we just measure them who has a 20 sbt ?

[Dean Romig]

That makes perfect sense… who has one?

Bill Murphy, I think.

[Steve Huffman]

Bill Murphy, I think.

Bill let us know what yours measures and I will measure the other 4 and get back to you !:rotf:

[Mills Morrison]

Bill Murphy, I think.

Pictures please

[J. Scott Hanes]

Measured per the diagram on p.45 in the Serialization book, the SC that I have measures:
1.70" at the frame
1.69" at the bolster
1.61" at the hinge

[John Davis]

According to the chart:

1) The only difference between a 1 frame and a 1 1/2 frame is the measurement between the pins. (Which has no application to an SBT)

2) The only differences between a 2 frame and a 1 1/2 frame is the measurements across the bolsters and of the standing breech. (Neither of which can be used to make a comparison between a Parker SBT and a Parker side by side)

3) That leaves only the measurements across the breech and the hinge. (Which are the same for all three frame sizes, ie 1 3/4 and 1 5/8 respectively.)

And of course, the "1 1/2" frame SC 237938 measures 1 3/4 across the breech and 1 5/8 across the hinge.

So, all that got me nowhere.

[Bill Murphy]

SBTs are not assigned a frame size. The 1 1/2 mentioned by one poster is just to fill in a blank column in the stock book. All 12s and 20s are the same size. I have a 20 with an extra barrel in 12 gauge that is off another 12 gauge gun, fits perfectly. My 34" 20 also has an extra 34" 12 gauge barrel that fits just fine.

[Dean Romig]

Thanks Bill, that settles it then.

[John Davis]

Bill, reasonable explanation. However, me thinks you got lucky with your 20/12 SBT. None of my 4 Parker SBT's are interchangeable in any manner. At least not without a lot of filing and fitting.

[Bill Murphy]

John, the extra 34" 12 gauge barrel for my 20 gauge 34" SBT is not a perfect fit, but it works and shoots and I will get it properly fitted some day. It needs a thicker bolt plate. The extra barrel for my other 20 is a perfect fit and I shoot it regularly.

[John Davis]

Bill, you are a lucky man.

[Bill Murphy]

Lucky and broke.

[Reggie Bishop]

I would love to just see a 34" 20 gauge SBT!

This great gun was offered on gunbroker a few short years ago, purchased by one of our members. I sent him a packet of documentation and provenance on the gun that I had received from Dick Baldwin. He beat me on the gunbroker auction and I congratulated him because we had become friends at the Fall Southern and he, Linda and I shared meals together. I sent him enough of my voluminous information on the gun that I had acquired from Dick Baldwin and the previous owner that the owner of the gun wrote an article on the gun in The Parker Pages. Bob Beach of Griffin and Howe shared information on the gun in the decades after the original owner. The family dealt with Abercrombie and Fitch to sell the gun. The PGCA member and author of the article passed away and his family placed the gun on gunbroker to sell. I purchased the gun from that auction. That is what you have to go through to own a gun such as this.
