[ARC5] NXsa-38075?

[Christian R. Fandt]

David,

I stole a bit of time to check my decent ARR-2 setting next to me (that 
I've been working on cleaning up) and a couple of ARR-2s I stumbled across 
a few weeks ago in the storage garage at the back of the property (got so 
dang much stuff stashed here 'n'  there that I plumb forgot I had 'em. 
Still don't know when and where the heck I got them. :-\ )

Anyway, here's what I have:

R4A/ARR-2   NXsa 38075  s/n 20949:CW

R4A/ARR-2   NXsa 38075  s/n 15669:CW

R4A/ARR-2   NXsa 21693  s/n 2512:CZR

The only unit that had anything resembling "dates" stamped upon it was my 
good one, #3 in the list above. However the stampings are not typically 
what I think are acceptance test dates. May not even BE real dates. Could 
just be mod info. Stamped in white ink near the top of the front panel 
between the two tags is "TN   87  44" and stamped in white ink just above 
the bottom of the front panel is "156  OH  7  53". No other stampings 
indicative of dates, modification orders, acceptance, etc. are anywhere to 
be found on that unit.

Both of the other units have a small anchor with U and an S on either side 
of it stamped in reddish-orange-colored ink on the upper left of the front 
panel. Looks like the typical Navy acceptance stamp. Nothing else 
observable on the units, especially as to dates.

I discovered another neat thing: it's a C37/ARR-2A electric tuning control 
adaptor, NXsa 36952,  s/n 18777:CW. It was laying separate in the box and 
both ARR-2s had adaptor plates for this motor drive bolted to their front 
panels (just one C37 though :-\ ).

Is there an online ARR-2 manual to be found anywhere?

Other treasures I found in that box were a BC-451A, BC-442-A, RE-2/ARC-5, a 
partially dismantled (grrrrr!) C38/ARC-5, and partially dismantled BC-450 
(well, I've got two good ones of those).

Hope this helps.

Comments on the C37/ARR-2A?

Best regards,  Chris F.

< Still racking my brain as to where the dickens I got these 
things.  :-\  Oh well, I found a half-dozen other boxes unopened that may 
yield yet more fun and surprises! Probably not mil-related, but 
nevertheless interesting to rediscover what they are. I have TMS syndrome. 
TMS = Too Much Stuff. Rapidly approaching TDMS (Too Damn Much Stuff). 
Looking to start therapy soon before TFMS sets in and my wife diagnoses it!

NNNN
