There is an entire "wardrobe" of NEF and H&R stocks for my NEF frames in my collection. All but one have been re-shaped to fit my hand and to better fit the frame. You will find that all stocks interchange, but a stock that is flush with one frame will be proud, or alternately, below the metal, on another. The yellow birch that NEF uses can be stained to a very pretty walnut tone, or anything else you might like. I have had good results with Tru-Oil, and even better with Minwax Antique Oil, as a final finish. Re-finishing the wood is part of the fun of working with Handis. It is addictive!
