I would have to have those rifles in hand to be sure , but; my first thoughts are those may be the original stocks that have been re-worked. The curved top line at the receiver front ring are typical of original stocks. The bottom line of the butts may have been reduced to make the pistol grip stand proud at the bottom to allow a new grip cap to stand alone. I have seen this done and done it myself and that's how they look afterwards. The original checkering may have been removed and re-cut in skip line. Again, I would have to hold them for examination to be sure. The work was well done. They appear to have a new matte metal finish on the receivers. So, they are not collector pieces for sure. If the bores are very good they might just be fine hunting rifles. I wouldn't consider more than 2500.00-3000.00 for the pair if the bores are bright and fine. And, I would enjoy the heck out of them as hunters and if possible re-cut the checkering to remove the skip lines. All depends if the wide lines are exactly double the normal cut lines to allow eliminating them.
This sort of comment is a real problem with honest people attempting to sell desirable rifles and it is, sadly, all too common where such aspects of our sport are concerned.
I would like to SEE this pair offered in BC, for the $2500-$3000.00 mentioned above, that is simply [bleep] ludicrous. I have bought and sold and used P-64-70s since 1968, owned 43 to date and currently own a dozen very nice specimens, 10 originals and two "customs".
I HAVE a pair much like this, a .300 in 95% original finish, hardly used and a .375 which has only the double-bolted replacement stock, unfinished wood, that WW supplied as so many stocks, especially in magnums cracked in the action mortise between the trigger and mag. box, and in 93% original condition, both with pristine bores.
I had matching Borden-Rimrock synthetics installed by one of the two BEST men in BC, both did and may still do the synthetic-stocked rifles for BC/Canada's premier gunmaker, Ralf Martini, and these rifles are gorgeous and they SHOOT. I have Talley QD bases on one and Leupy QRWs on the other and lots of fresh components, dies, etc, for both.
I want to sell these, three of my four Alaskan .338s, my Fwt. 30-06, my "Westerner" .264WM and maybe my pair of Fwt.-.270s. I have had them at the finest gunshop in Vancouver, but, this is not the "guntown" it was in my youth and most customers of gunstores here now are Asians and "Wannabes" who spend thousands of $$$$ on "black guns" and "rifles" such as the Tikka T3s......
I would consider someone "offering" me $3000.00 for these as an insult and would either just laugh or tell such a character to GFY...and, back that with whatever seemed necessary at the time. Rifles, like these are VERY,VERY hard to find, my buddy sold a nice, not completely mint Alaskan .338 about a year and a half ago for $2800.00 and I would not expect to find one in 90% or better condition for much if any less.
I cannot tell from photos, but, as these rifles, only, sit, I would consider $4-5K, about right for the pair and mine will NOT leave home for that figure. "Lowballing" on the internet actually hurts all of us and is not going to make "sweet deals" available to anyone, it just confuses legitimate buyers and sellers.
I also think the stocks are reworks, this was commonplace back in the day and often done by locals with more "wishin & hopin" than real skill. These look OK, but, detract from the value of a pair that in original condition and showing minimal wear as depicted would be well worth the 7K asked....they ain't making more of them.
