[ARC5] Mystery Command Set remote dials

[hwhall@aol.com]

I have a question about a couple of stray dials here. These appear to be Command Set remote tuning control dials. One (on right in attached composite photo) has the expected knurled thumbscrew for attaching the dial to the control unit. The other two have instead three holes. Note that the thumbscrew dial has the same E5614 number as one with the holes.

The ones with holes have an "ARC" stamping on the reverse side along with different part numbers. The .2-.55 dial says "PART 12555". The .52-1.5 dial says "PART 14041".

I've drawn only blanks looking for these part numbers online & in the ARC and SCR manuals I have downloaded. The closest I found was part 5610 which is .52-1.5 for the R-24 set, and part 5613 which is .2-.55 for the R-23 set.

Any insights out there as to where these belonged? Maybe not Command Set material at all, but where would I start looking?

Thanks!
