A twelve gauge 1-Frame is a desirable gun, especially in a DHE. I don't see any Remington codes though.

Scott,

I would shy away from heavy duck loads in a 1 frame. I have two of them and at a round of sporting clays 7/8 oz is all I want. A box of shells in the dove field is OK with 1 oz loads. Out of deference to the lite 12 gauge and my shoulder 1 oz is all I dare out of that frame size.

OK, no Remington repair codes, so any factory modifications would have been performed before the Remington takeover. We would have to see better pictures to determine whether we think Turnbull case colored the action. I have my doubts. Besides the water table which doesn't look too much like Turnbull colors, I doubt that a week at Turnbull's (as you suggested) would get you a case color job. It's a nice gun, the forend should be repaired by a professional, and there just aren't any other problems. All this special care for #1 frame guns is not neccesary. A #1 frame gun is the same size as a #1/2 frame gun and Remington made trap and skeet guns on the #1/2 frame.

Nice gun...What interests me on the barrel flats is the 2.5 and 3 stamped at the breach. Chamber length? Any ideas? 3" would be a little scary for a 1 frame gun though.

Turnbull said that they believed just the metal was sent in for case colors and the work was done that quickly. BTW my photo skills leave something to be desired. The CC appear very differently in photos of the same part largely due to angle and reflection from lighting.

The 2.5 could be the chamber length, although I have never seen another with chamber length stamped...
The 3 is the grade stamp for a D-grade gun and is in the correct position for the grade stamp.

If you want to hunt more than work less. Either way if your succesfull dinner is on the table:corn:

I confirmed the forend is original. As you noted, the forend of the gun needs repair to the wood and I believe to the works as well. When the forend is mounted on the barrel, the extractors protrude from the breech. When the barrel is mounted on the gun, the forend resists closing completely unless forced. Would you all recommend Turnbull for both repairs?

I recommend telling where you are located and meeting with an experienced Parker collector who can examine the gun and tell you what is normal.

I agree with Bruce. You need good, hands-on advice before you go shipping it off to anyone.
