Wolverine Adjustable Comb Work

I like my Wolverine HP R except for the cheek weld. I have a piece of foam attached to it and it works well but is not a neat set up. I see some folks in the UK modify the standard stock for an adjustable comb but I haven’t found anybody Stateside that does the work.

Has anyone added an adjustable comb to the Wolverine in the US and, if so, who did it?

Thanks for any suggestions

Mike
