The 3 1/2 barrel, red post, two tone aka pinto,and birdseye stocks were most likely all requested.I find it pretty neat that the unrelieved stocks predate the revolver by quite a spell.
I bought these S&W early K-frame stocks made of birds eye maple on ebay about a year ago. I don't know how many pairs of stocks were made using this wood, but you don't see many.
