I think too late now, but a couple of years back, saw one in the corner of a Gun Shop & the restocked rifle (in more modern style) in the rack, I was going to buy "just in case" but the Shot Gun trigger guard would be a pain to make !

Only saying as you never know where you may find one, I looked at a M21 yesterday in 8x60 (Rare ?)
You wont believe this I should of taken a photo, drilled & tapped for SIDE mount & stock cut out for it, then some one fitted a Quick take off Claw Mount, nicely to, all this on one of the only early Mauser's grooved for a scope ???
