Thanks! Ironically, I scored another MIJ Club Date kit yesterday; 20/12/14/14. I showed pictures of it to one of my MIJ Facebook groups, before buying it. It's called a "Extra Play Brand Super", from 1967. The consensus is that its Pearl made, it's fairly identical to the Pearl Valencia model. I now have three MIJ kits that are 20/12/14 (two of them have matching snares as well). Lucky, I guess. Cheers.
Measure the BD shell depth. Is it a 15 incher? I have a Pearl made kit similar - BD shell is 15, not 14.
