belkrem, I like what you're doing! I like the maple leaf design - it occurs to me that after staining & finishing, filling in the groove with, say, bright red epoxy (similar to cloisonne) would help to set it off (just my personal taste, of course!). I would HAPPILY put a set on one of my 1911's.
Keep us posted! If & when you get geared up to the point of commercial production, I will be one of your first customers!!
