[Milsurplus] ARB surplus dealer conversion on Ebay ?

[Hubert Miller]

It looked to me that this ARB was first a surplus dealer conversion ( maybe the local tuning) with the rubber stamped band “content” marking. I can’t see the hamifier doing that, can you really?
In fact, I “may” have even seen an ad that sort-of corresponds, i mean touting the same band “content” for its ARB offering.
Then it looks like additional hamifications were added. This is what i was asking about, your opinions on that. We DO know ARBs were modified by some surplus dealers in CA for marine use.
Along with a modified BC-375, i believe. Yes, crystal controlled.

I suggest that living in WA and OR port cities for many years, i have seen a greater variety of the old 2 MHz boat radios than many. Northern Radio had tunable band options on their over-under
style AM boat radios. You could buy the receiver with one tunable band, AM BC, and the other channel positions fixed crystal, or you could mix and match, crystal channelized positions and tunable
bands up to 18 MHz.  The receiver sections could also be purchased as separate stand-alone units with the same options.
Many years back i gave Ken Lakin ( sk ) a Northern 150 watt transmitter and PS. I kept the receiver section as it was one of the less common variants with tunable bands thru 18 MHz. Very few
Northerns were sold with tunable band options for the HF range above 4.5 MHz.  This large heavy AC powered unit, about 40 inches tall, i was told came from the Everett WA police department –
for port operations, not land mobile communications.
Other NW manufacturers PAR and Intervox also had HF tunable receiver sections to their boat radios.
I do not know why it was done that way up here. I noticed Apelco even in its high-seas radios – HF bands and higher power, 150-200 watts – did not have tunable HF bands on their receivers.

The quality of the workmanship on that conversion excludes just about any commercial modification other than personal use. Any boat large enough to have 120 volts AC would have real type accepted radios and no need for something like that. I can see things like ARN-6 and 7 sets along with Loran sets being adapted and used but with the exception of radios like the TCS or other radio combinations with the ability to have crystal controlled transmitters cannot see anyone going along with attempting to use something that cobbled together in a commercial application.
And from what I remember HF AM marine service at least in all the small civil craft had to be crystal control on the transmitter in order to meet type acceptance, maybe they had tunable receivers but I never saw any tunable receivers apart from the AM broadcast band and the low beacon band on any of the old AM marine radios.

Probably modified for marine use after WW2.

I see nothing but a typical grossly ham-modified ex-ARB.

George has an ARB on Ebay

I wonder if anyone has seen this commercial conversion before. The crudely cut and stuck on Dymo labels are user-added; i mean the
stampings indicating bands. I don’t think this is a “marine conversion” because i believe marine users wouldn’t need the really basic
band markings like “SHIPS” or  “SHORTWAVE”.  The plain alu panel in the lower right also looks a bit crude for a commercial conversion.
What think?
I have a BC-348 with a stamping in the upper left top, “MODIFIED FOR A.C.  READ INSTRUCTION SHEET”. I thought at first it might be a
( original ) factory conversion but the A.C. PS is not up to OEM quality.
