It looks a lot like this one - National Military RCK - maybe a different revision.

A military version of the NC-100.  The '100 has a similar system of band change and dial: HRO type dial, and holes in the front panel with an indicator to tell which band is engaged, as the coil catacomb assembly moves across.  The NC-100 is general coverage, and the NC-101 is the ham band only version.  Later, they came out with the direct reading dial on those receivers to replace the HRO type dial with the frequency charts, and the model number of those sets had the -A suffix. As seen in the photos, the military version included a 200-400 kc/s longwave band.

Looks like Hammy Hambone got his mitts on the receiver shown in the photo, and replaced the National band changing knob with something that resembles a Collins type knob, like the ones on the 75A-4.  I'd bet it's fun trying to grip tightly enough to rotate the band change mechanism using that tiny little knob.

RCF, RCK, or any number of NC-100 custom builds for railroads, airlines, Canada govt (their airlines and railroads were nationalized back then.

Very few specific schematics exist, you have to pick thru them all to get close and then draw out the rest. Most changes were in ANL, squelch/tone signaling and audio outputs.

Many commercial variants had the same band. The fact that it appears to cover only 4 ranges might be a clue.

Ok. So late 30s national for commercial or Govt use. Got it.

Ive heard they were built into the very early post WW2 period until the NC-240C and 240CS replaced them sometime in 1946.

Ah.. Ok.  Neat little rig.  Thanks for the info carl.

Yo'

   Don't recall where it is now but mine was from Mansfield's Laum (SP)
Airport. Was modified by the "Shuttig Co." with squelch. Worked pretty
good as I recall. Don's right about that knob. Between bands it was
smooth as glass but getting all those pins into the detents required
some force.  Sorry about the crappy pix, had to scan an old photo.
Hadn't thought about it in 20+ years.. Thanks!
Mine was a "CAA" order number.

Tell us about that Warsteiner receiver.

[N8ETQ]

Hey Steve,

   One year, around Christmas, It must have been the mid '80's Warsteiner
sold it in a 1.1 Imperial Gallon Kan/Ceg. It came with a
little tap and 3 legs, and a couple of those bumper stickers.

   Myself and Dave Ramser KG6AB picked up a 6 pack of em.
It was gone by Dayton. Good schtuff.
