[Boatanchors] Help identifying some transformer & choke iron

 This one is definitely a high voltage transformer; the secondary leads exit out the top of the covers through grommits and are marked HV. It's a heavy piece of hardware.

Thordarson T55s at one time were audio transformers, for getting mic 
low Z to high Z to drive grid, or output plate to line Z to drive a 
mixer.  But their designators were T55 followed by a letter and not a 
number.  I'm talking about the late 1930s.
