This is the older TKL Spector case. I actually prefer these older ones as I have 10 of them...
One thing to note is if it's a NS-4 case (thats just what PJ @ Spector calls it) then it will fit the 4 string Spector's and some 5 strings but will be very snug on the 5 strings... Sometimes too snug.
If you have a Spector and looking at this case I would suggest getting the actual dimensions on this from Beaver @ Bass Central. Post here and I can tell you if its a NS-4 or standard.. The NS-4 is smaller and Std is longer and wider.
