[ForSale-Swap] octal filament regulators? FS and/or ID

[Eric Jones]

de N4TGC Eric

In scouring for another filament regulator for the AM-65 that powers my 
RT-70, I've come up with some that don't fit, and can't ID.  Hep?  Moi daze? 
I'm dazed?

Amperite 115N05 relay
ditto 6N012Q? D? 0?  (can't tell - number on base is also unreadable)
Amperite 115M045  (base #8195958)
ditto 115F30 relay

Can anybody squirt or point me to an Amperite relay catalog?

Some even weirder octals are what appears to be a giant crystal plate 
suspended between wires, made by Northern Engineering Labs.  I can see a 
'kc' marking, but the f. is rubbed off.  Another is a single-pie dual coil 
in the glass envelope.  The only clue is the number 1212893 on the octal 
base.
