Hi, Mike,
Sorry about the delay...job interviewing and running around all week.
Okay, my tank is blue, anodized aluminum, I THINK it is 80CF, but it has been so long since the last time I filled it, I'm not certain. When I go into work tomorrow, I will check.
The tank is in perfect condition, has never been outside. I keep it at my lab (work) because we have all this land on our site. When I bought the Talon SS, I immediately realized it was too loud for my suburban neighborhood. Consequently, I really only shoot it on summer weekends when I have to be at the lab...kind of a shame, because it is a sweet gun.
Tell you what, I'll pm you with some pictures and details of the tank, can you do the same for the Big Cat?
Look for my PM! -JC
