SC on Gunbroker
 

Check out Item number 553896534 on Gunbroker. Is that a replacement stock?

Yes

there's no checkering on the side panels of the stock. Is that the indication its not a factory stock?

It's one of those real early prototypes from 1902:rotf: The more you study stock shapes, checkering patterns, and checkering borders will, in most cases, help you identify original Parker wood. There are some stockmakers past and present that can fool you.

Lack of checkered side panels, completely incorrect wrist checkering, the shape of the cheek panels and how fat the wrist is are all indications of the stock not being original. And the fact that it was built in 1902 as Chuck pointed out.

The comb is ok looking...

the seller tells me the ser number is 185508 which would make this a 1919 trap gun

Well, for what I consider short money, I'm buying this trap gun whether the stock is original or not. I need a trap gun and this will do, not as a collector but a shooter. Turns out tho, the real owner of this gun has other Parkers he may be willing to sell and I'm expecting a call. So, all in all there may be some gold behind this hounds tooth! Lol

looks like a nice enough gun to me.. I'd like to find a PG SBT with a bad barrel. I figure it would make a heck of a nice stalking rifle.

Thank you Edgar. I spoke today with the sellers, they're a married couple in their 80's who've owned their sporting good store and gun shop since the early 60's. They're handling this sale for one of their local customers whom I expect to speak with in the next several days. This gentleman, I'm told, has other Parkers he may want to part with. Another 20 ga Parker or 16 would be fine by me regardless of grade. I've wanted to pick up a SBT for awhile but didn't want to pay a small fortune as I shoot trap intermittently. This one will work out fine.

Looks like there may be cracks in the for-end wood that may need to be fixed.

No Chuck, I inquired about these and was told they're just scratches in the finish. But I thought the same thing from the pictures.

Good, enjoy the gun.

I am looking for a donor SBT to do the exact same thing to. I have a monoblock and Forend. I want to do a 2 barrel deal. Rifle / shotgun.

What caliber? 45-70??

Not really decided yet. I am thinking about. .35 rem or maybe 30-40 Krag. I need to sit down and do the pressure calculations and settle on a nice caliber for the action. I do not think i want to go bigger than .35 cal.

Without a top locking lug or cross bolt, cartridge is somewhat restricted to lower velocity/ pressures. As much as I enjoy 45-70, I think a flatter shooting round is more appropriate for this type of gun. As Brian suggested, there's nothing wrong with the old timers like 30-40 (.30 US), .303 British or .300 Savage. For simplicity, I'd stick with the rimmed cartridges, but don't I wish that action could handle .375 FNE.

.300 H&H ???

Any belted magnum would be too much, in my opinion.

I agree. It may realistically hold up, but most would not take the chance.

I am sure that any cartridge that was roots to the turn of the last century could be loaded right to work on an older shotgun action. But who wants to build something that needs a safety disclaimer attached to it.

I've always liked .405 WCF

a 35 whelan would be nice....but the old 30-30 and the 35 remington are good choices too...charlie

Hmmm. I guess I wonder how a 12 ga shotgun would wind up with a .30 or .40 caliber bore? Sleeving?

Are you thinking the action isn't strong enough, or the barrel, or both? I'd think there's plenty of opportunity to make the chamber strong enough.

Edgar,
I did some calculations using Ellis Brown's formulas for building rifles on shotgun actions.

A 12g. shell with max average SAAMI pressures of 11,500psi ends up calculating to 7,086 psi of force against the breech face. That is a safe number given use of any factory 12g. load. Not talking proof loads.

I calculate the .35 Rem to be well under those pressures with force against the breech face being only 5,564 psi.

The 30-40 Krag calculates to 9,326 psi and the .32 Special is 8,441 psi.

So, based on the numbers, the .35 Rem looks like the best option.
I am sure that realistically the others would be plenty fine as well if one were to adjust the 12g calculation upwards to factor in proof pressures. But why push the envelope.

I'm not sure about the pressures of 30-40 Krag vs. 35 Remington. The 35 Rem is a lot hotter than the Krag. I know the 8x54 Krag has a chamber pressure of 42Kpsi, and as I recall, .30US was less than 32Kpsi.

I may be wrong, but I think you're oversimplifying the problems that need to be considered in chossing a cartridge for this action. The distributed force over a smaller area increases the stress significantly. The 12ga forces are distributed over .62 sq in, but the 30US, and most similar 7mm, .30, and 8mm cases are less than .2 sq. in.
Also consider the action type; the center line distance of the SC, above the pivot point (Front lug) is close to 3/4" while most center fire cartridges are in line with a bolt face. The further away the center line deviates from the from the points restraining it, the more important a top locking lug becomes.

I love the 8x68S but I wouldn't subject it's 52,600 psi chamber pressure to an action design to restrain 12kpsi

This also does not take into account the rapid drop of of pressure is a shotshell vs distance from the chamber as opposed to the progressive burning powders where pressures are still increasing away from the chamber.

Do you recall seeing the stalking rifle in the rack at my table in Baltimore? It was a wonderful single shot in 9.3x72, and it had a single locking crossbolt, in addition to two locking underlugs. There must have been a reason for three locking points, above, and below the centerline of the cartridge.

After receiving the Parker SBT from the seller in Michigan, I shipped it back. Too many issues with this SBT. Took it to Cullity's for inspection as I noted a number of issues. The ejector mechanism requires serious work, the inside of the fore end had been re-worked improperly, the top rib had several sections of non parker rib material installed (patched in)and the rib wasn't even level. Just too many issues and would have been a money sink to correct so I declined the purchase and shipped it back. I'd do better to pick up a BT-99 for all the trap shooting I do.

Brian have you thought about the .35 Winchester? Ballistics fall between the .35 Rem and .35 Whelen and cases are easily formed from .30-40 Krag cases. Even without max loads it puts deer and bear down instantly and psi should be similar to the .30-40
