I got this recently with another bass but I no longer need it. It appears to be a vintage Modulus molded hard shell case
that's in great condition. There are no rips or smells on the inside and all the latches work properly.
It looks to me like it was originally made of a Modulus Quantum 5 Bass
but I can't say for certain because I don't own one. The inside length is 47"
and the body shape looks like a Q5 to me.
I'm sure some other basses would fit in it as well so feel free to PM me any dimensions and I will be glad to check for you. $65.00 Shipped and Insured in the CONUS PHOTOS CAN BE SEEN HERE: https://www.dropbox.com/sh/oh5etcg06jzxqui/uFy-0SpVHE
