misslead; I do have a plastic stock for a MK V with a #2 barrel channel. It is the right stock for a .257 Wby with factory barrel, unless you have a featherweight. It looks new.
Also have a wood Mk V take-off #2 barrel channel that has age cracks in the varnish. It will have to be refinished, but the wood is beautiful; at least AA, maybe AAA.
If you're interested, email me at email@example.com
Good luck, Tom
