10-string Melobar is indeed a Mosrite-built instrument, one of a quantity of 500 that Semie Moseley produced circa 1965 for the Smith Family, the company behind the Melobar name. Apparently 500 of this design were built: 50 finished in white, 50 in blue, 100 in black, 100 in red, and the remaining 200 in sunburst finish. We previously looked at a sunburst example here.
This intriguing instrument - I'd love to have a go on one but never really got on with slide guitar - is currently being auctioned on eBay with a starting price of $875.
