Were any of those for the original 1226? I bet all were newer "supergrades".
There are all manner of abominations done to those original 1226. The collectors want pristine, original, and all the parts present. Some of the parts are so expensive that if missing, the gun loses all its value. I've seen pristine examples save for a bobbed barrel sit on the market for a decade at $5500. (21" barrels were a thing)
The rear sight is prohibitive and exclusive to the 458. $500 and up. (missing on the example in this post)
The bottom metal is $500 and up.
The supergrade sling studs are very expensive.
Original unmolested stocks that haven't been cut down, had new crossbolts added, and have the original pad are many thousands of dollars.
The internal 458 box magazine is very rare.
As you can see, if those parts are missing, you're left with a $700-$900ish pre-64 action.
Inversely, an all-original but totally trashed pre64 458WM selling for $3500 is literally worth the sum-total of its parts if chopped up.
There is not enough originality left in this gun to put humpty dumpty back together again.
