Mike,
They would be a perfect start for a double but I need the RH one for a customers gun. Ordinarily, I would tuck the LH one away because 'I might use it sometime' but my 70th birthday is tomorrow and odds are slim that I will ever use it. Also, the thought of making all the mirror image internals is too intimidating for me!
Now that the shop has CAD input for both sides, I can have them make you a set for your double.
Jim
