I guess you did Wade. Based on the number, there are 4 elemnts (5u4) and a 5v filament, so I guessed it was a rectifier and not much use as a class B amp tube. Didn't know the price value of the tube, but I'm guessing it's more than $2. I'm gonna google it just to find out, but I won't post it here.
73
P.S.
I believe the filament is also the cathode for the 2 plates, ergo it is a full wave rectifier.
