[Milsurplus] BC-221 Headset

[J Forster]

I was looking for the appropriate headset for a couple of BC-221s and
bought a pair of HS-30s NOS/NIB in wax dipped boxes from Fair along with
a pair of NOS C-410 transformers. Unfortunately, the transformers came
with PL-54s.

Am I right in assuming I also need  "bailout" cords. Does anybody have
the cord number handy? I can't find my TM 11-300 at the moment.

Thanks,
-John
