I think that Manners makes one like your looking for but I don't think they use the thumb wheel.
Tery Cross makes the adjustable comb hardwear that Manners uses and its a very good rugged desgine I used it on my A5L for my 260 and will likely use it on my A5L for my M-7 6x47 Lapua.
I know that Terry won't work on the Laminated stock but I'm pretty sure that he'll work on all the others , you may want to give him a call and see what he can do for ya , maybe you can just have one installed on your HS !
