Yep, it's a Talman. There were quite a few different configurations available, as well. I used to be in love with one at a store here in town that had two P-90 type pickups, but could never come up with the cash for it when I was 14-15.
Nah, it's got a volume knob behind that Bigsby arm. If you look closely, you can see the word "volume" going vertically. It just blends in VERY well with that pearloid pickguard.
