(Years go now) a friend put an LM out at his spot at the big Gaithersburg Hamfest. When he came back, someone had left two more to join it. I think none of them sold!
I have dug into the "needs repair" power supply here - it is Coast Guard Power Pack for LM-7 Type GF-118, 1942:
-Original iron replaced by newer non-military transformer and two chokes
-Rectifier jumpered by diodes
-One of three oil bathtub caps clipped out of service (2uF 600v)
-Two-prong line connector has line cord soldered on
-Original power outlet connector still present
This thing needs overhaul but will serve well once set right.

I think hamfest price is around $10, not much more, for LM and BC-221.
