Tony, the picks sound like they have to be a discontinued line of D'Andrea. I'm sure if Scotty Moore talked to Tony D'Andrea he'd do his best to make him happy. They have a website, but the catalogues are narrower than in times past. They've moved since the address listed in PICKS!, and I could find the new building address if the web mail doesn't suit. But D'Andrea does the parti-colored and tortoise-shell celluloid you describe--the material is the same but the particolored always seems looser to me, maybe because it's constituted from bits rather than tortoise swirled-- but they have tried many shapes and things over the years--probably still have the dies. They still have the mallet die Tony's great grandfather used to pound out the quintessential flatpick shape.Yep. Nobody has figured out how to stabilize celluloid since John Wesley Hyatt developed it in the 1860's, with gun cotton and collodion, trying to win a prize for making billiards out of something other than ivory. (It worked, but the balls would sometimesexplode, causing everyone to draw their guns and look around at each other.) Nearly everyone is at least expanding into other materials, the only things still made of it are picks and ping-pong balls (which some people use for nail-extension or repair). The edges seem like a simple downgrade in production standards to me. National, as far as I can tell, is an imprinted name, owned by somebody else now. Sorry I can't be more help, but for some reason good things go off the market.
So MMario, do you mean, you think maybe? arrowheads?
