[Milsurplus] Navy-badged Collins 51J receiver photos?

[Nick England]

The Navy evidently acquired versions of Collins 51J-1, 51J-2, 51J-3, and
51J-4 receivers.
I'd like to add photos to my Navy Radio web site of these receivers with
actual Navy ID tags.

If anyone can help with a photo or point me to one on the web, I'd really
appreciate it.
I am looking for photos of the following Navy-badged rcvrs:
R-381/URR-23 (51J-1)
R-381A/URR-23 (51J-2)
R-388/URR-23A (51J-3) and R-388 with NoBSR contract number
R-388A/URR (51J-4) (has anyone actually seen one of these?)

Also I'd really appreciate any photos showing these rcvrs installed in a
Navy ship or shore station.

Heck, while I'm at it, how about a photo of Navy-badged LS-175/U and
LS-199/U (matching Collins speakers)?

cheers,
Nick
