bowlback manlolin

this looks like an old handmade bowlback mandolin, the wood is nice, maybe walnut and cherry or maple?very light weight, 8 strings, metal tuners with ebony tips and ebony fretboard? the tail piece is a thin metal, maybe tin, could be steel, the inlay is not  one piece, but the edges are turned up so i don't think it is plastic? has a turtleshell look with ivory ?  pinstripe separate. I cannot find a name, initial, #, trademark, nothing of a hint of who,where,when.
