Rare Classical Guitar w/Patent # For Special Neck

Very rare classical guitar, #CG-43, built by Velvet Touch, has a patent number from a patent taken out by a Cleveland area gentleman. The patent is for a fretboard embedded on an elastomer rubber to help players use less pressure to push down on frets. May be one of only a few ever made. Extremely well built, perhaps by a Cleveland area luthier , or Japanese .This has, I believe, a solid wood top , back, and sides. I put a light inside the body and looked at the insides with a mirror, and the grain markings on the outside matched the ones inside. Great sound, beautiful workmanship, not sure of the woods used. There is one thread on an acoustic guitar site that a man describes having one his parents bought at a Cleveland music store when he was young. Patent number on the label can be looked up in the official patent file and has pictures and explanations of the patent. Patent No. 3,791 ,253 will take you to a 4-page patent filing. $175 cash, local pickup preferred. Thanks for looking.
