[Milsurplus] Navy RCA SSB-1 questions

[Nick England]

I've acquired one of these SSB xcvrs and had a good time reading past
discussions about them on [milsurplus]. Does anyone have a photo or drawing
of the complete unit? - I just have the RF section and not the p/s. I assume
mike/handset connections were made on the p/s chassis?
See photos of mine at http://www.virhistory.com/navy/xmtrs/ssb1.htm
Also mine only has two 6146's instead of three mentioned by others. What
version does that make it? Vintage Manuals has an SSB-1 Mk II manual but
before I spend that much, it would be nice to know if that is a useful
manual.
cheers,
