Brad:Someone had a post on here in the last 2-3 months for a complete set of factory wood that included the forearm iron for $650.00.I would start in early Dec and research the old threads..John KS-OKIE.
I am sure I have a nice one with an adjustable comb and no checkering. I will look to see how much the cast is. I bought it because it was 14.5 lop and had more of a "neutral" cast and my F3 stock. I decided I prefer a shorter rather than longer stock for clays.
If you are interested I will dig it out and take a few pics.
