[Milsurplus] P.A.R. boat radio

[Hubert Miller]

Well, Bruce, I had wondered about the dynamotor, would they have gone through the expense of buying a 32 volt one ? Your suggestion that they used
a 24 volter makes sense to me. After all, they heavily used surplus parts in this. I don't know if others noticed, but the meter looks like out of a 'Command
Sets'  RF ammeter box. 
The set is weathered looking but when you pull out the chassis, you note two things: how smoothly the chassis slides, and how clean and neat it is inside.
That's a antenna variometer in one corner.

I have two others which are in wonderful shape, same radio, but the PS is not based on the BC-456 thing. I sent the photo of this one because of the 
interesting power supply. The power supply does include a permanently attached to-radio cable, and the connector is a military connector, can't 
recall right now but looks like an LM or RBM sized connector and pin count.
I sent a previous photo of a P.A.R. modified BC-654.  When I looked inside this one here, I was thinking, how can I get that BC- 654 modified thing, what 
could I tempt the owner with ?

I have another small P.A.R. radio which I think may be the lowest cost boat radio ever. The receiver is also tunable, 1000 - 3000 kHz; there's a lever to 
push to talk, and you talk into the speaker. I recall seeing a bunch of these at Pacific Surplus in Seattle, on First Avenue, which was then Skid Row. None as
I recall of this cheaper radio looked finished, so I think maybe it was a last product when the company went under, maybe 1953 ?

The styling is great, especially for a small company building rigs from surplus and generic parts. I am making an educated guess the receiver is powered by a vibrator supply, a 28 volt dynamotor should be able to run intermittently for transmitting on 32 volts without any real issues. Getting a 32 volt vibrator and power transformer for the receiver would have been easy at the time, it was still in wide use in distant "off the grid" farm houses as well as yachts.� Many builders of post war private aircraft radios used surplus dynamotors. They touted them as being more reliable� than vibrator supplies, as well as safer because there were no contacts to weld.
