The frame size is a 7 and as far as unique machining or unique gun I have no idea. Tomorrow I'm going to send in a research letter request. I'm very curious what they can tell me about it.

Bill,
My 38" 7 frame has has a barrel marking of 10 9. It is about 400 serial numbers higher than this one. I think that the wooden case is very nice.
Dave Wolfe of Waco TX is also someone who could fix the stock on this gun.

A seven frame with 36 and 38 inch barrels that alone weigh 10 lbs... how much do entire gun weigh?? 14-15 lbs??

First, I love to hold one in hand... Second, I'd really like to shoot one some day.

Well Frank.... you're certainly the man to do it! That's something I'd like to see.

If there was ever a gun worthy of restoration, this would have to be it. Many (myself included) get weak in the knees over the small bores, but there is something about this gun that really talks.
Kind of reminds me of those huge armorers models of the 1917 Brownings, only this one is the real deal.

Assuming a well deserved and worthwhile restoration, were it mine, I would also be tempted to book a wildfowling trip to the UK, where I believe you may still use an 8 bore,

the logic being if you can only shoot a certain number of duck what matter is it what they are shot with.

the one British gun law I can agree with.

My gun weighs 15 1/4 lbs. I have posted this picture before.

Jeff,
I put mine on the kitchen scale and it showed it weighed 16 lbs. I don't know how mine with shorter barrels would weigh less, maybe the wood is heavier or the scale isn't perfect. The barrels alone weighed a just a bit less than 10 lbs. Very interesting...

I am planning to get the stock professionally repaired so that I can shoot it someday. Hasn't been fired since the 70's. Kind of a right of passage in my family.

16 lbs... what a beast. What's the heaviest Parker ever recorded??

Jeff's gun also has factory 4" chambers as I recall. It is one of a pair, different grades but identical features, again, as I recall.
