Brian, I have two 1 1/2 frame guns with that HRBP. It was also the style on the unfired VH shown here previously
3#8oz sounds pretty light for unstruck 2 frame bbls. Maybe Mr. Baker could get and accurate firing pin cl measurement.

Yeah, I got to thinking that the 1-1/2 frame also uses the same buttplate as a 2 frame.
That's why I added 1-1/2 frame the possibility. Firing pin spacing will not tell the whole story since 2 and 1-1/2 are the same. Will have to check out other dims such as breech ball width or height of standing breech.

I am surprised that the frame size marking is completely illegible. But, I have seen some stamped pretty light. Or maybe it was removed for some reason.

I have a VH #2 frame with 28" with weight of 3-15, & a PH 1 1/2 26" barrels with weight 3-4. Both have letters to confirm original barrels lengths and frames.

In this serial number range, there would be nothing unusual about either frame size being used, with the barrel weight of 3-8. The stock could be a #2 stock with the #2 style buttplate, and a #1 1/2 frame, nothing unusual about that. From Brian's posted frame dimensions, it will be easy for Chris to determine the actual frame size. Still a scarce gun and a great shooting gun.

Chris, you actually have an unlimited resource using this forum. The people answering your questions are doing so with respect for your gun and your concerns.. Use it wisely and all their knowledge will be reciprocated to you gladly...

the two old guns I had delgregos recolor were gone for over a year, seem like a problem with the math, two guns a year for sixty years comes to a 120 , but they sure look nice for old beaters . I was told they sub out the case color work or not?

I will get those measurements tomorrow. What are the open breech ball and the standing breech. I am guessing one of them is the breech face.

The easiest for you to check would be the width of the breech balls. Or in other words, the width of the breech end of the barrels. Will be 2-1/4" or 2-3/8". Check out that and the firing pin spacing on centers.

got out my magnifying glass and it looks to me like the barrel weight is three pounds eleven oz. not three pounds eight oz. Did anybody notice the funny line running across the rib about two or three inches from the muzzle. I don't look at many V grades but I havn't seen that before. Maybe it is gust the camera.

Ever wonder how many Parkers with problems, such as old broken stocks, were turned in during the steel drives of WWII? How many rusted/busted Parkers left in barns, damp closets, garages, etc were simply thrown in the trash dumpster after grandma died 20 years after grandpa died, 40 years after being set down for the last time? If my mother had found a shotgun in her dad's house with about 3" of splintered wood remaining on the receiver, she would have instantly recognized the gun as useless to anyone. Garbage pile. Subtract out all of those, plus add up the unknown number of Parkers which are still 1st and 2nd generation, same family ownership - Del Greco would have potentially refinished close to half of the remaining Parkers in existence, and there would be hundreds available for purchase on Gunbroker. 90,000 is one of the most ridiculous claims since Wilt Chamberlain. I will assume there has been a misunderstanding.
