Interesting. Hope you can ID it. The chassis is pretty generic and
that switch may be to select Broadcast/Shortwave - Shortwave often being
the old Police Band on such radios.
Again, I don't know anything about old radios but is there a chance that
the radio is in someway related to the Log Cabin Jamboree, a somewhat
famous fun variety and music radio show of the 1930s. Maybe a premium or
something similar?

I sure would like to see what the front of the chassis looks like when
removed from the wooden case. To me, the cutouts around the volume and
tuning knobs look hand-made. I suppose if a very limited number like
this were ever made they could have chosen to do them just that way in
the factory. What I'm going by mostly is the apparent overshoot at the
sides of the bottom of each cutout. Perhaps this was just where a
starter hole was drilled to make the cutout?
Perhaps someone knows what the standard manufacturing techniques would
have been in this time frame. i.e. Would routers with a guide jig or
something similar have normally been used? I suppose most all "high
volume" wooden case cutouts had metal bezels which would hide
woodworking inaccuracies. I'm guessing bezels were not used here
because either the volume was too low or they felt it would ruin the log
cabin look.

Having looked at it and it's construction would lead me to believe the
chassis came out of a damaged/trashed cabinet and the owner could not
stand to toss a good working set of electronics. It does have patents
listed for Hazeltine, as does my "Echophone Commercial" from around the
same era, and all large octal tubes. Middle 30's ?. This may be just an
outlet for a bored radio tinkerer who also did wood projects.
It could in all likely hood be a *one of a kind* keeper.
Cheers on the lucky find.

Note there is no tag on the front that says "log cabin" in letters
that resemble logs in the Bunis book radio. The one feature that
makes TwoMuttHeads radio look original, in spite of the crudley cut
windows, is the tag that says "log cabin". Just my two cent worth.
I added more pictures. Everything I see looks like a factory-built
radio. Inexpensive, yes, but not home made. I fired it up on my
Powerite and it does play. Needs the usual recap. The switch in back
does change bands to the upper range of the broadcast band, so it
would have received the "police" band. Now I'm trying to figure out
what they are using as the B- for the electrolytics (not ground).
Looks like a "newer" electrolytic was added.
Most likely the electrolytics go to the bottom of a resistor that provides
B- bias.
Yah, the name tag and matching panels with raised details are not something
an average guy could whip up in his basement shop.
The rest of the cabinet is crude, but hey -- it's a *log cabin* :-)
Phil
Heh, I just noticed there is no pointer on the tuning knob. I guess
that solves the problem of knowing where you are in the police band
since you aren't quite sure where you are in the AM broadcast band
either. :)

I would respectfully disagree that it (the cabinet) looks
"factory-built"; the radio itself, certainly is factory, but the cabinet
(and especially the cut-out windows) are very crude.
Has anyone yet brought up the possibility that it started out life as a
"real" Log Cabin radio, the cabinet was somehow damaged, and a home
woodworker said "I can make a new cabinet for you", re-using the metal tags?
Just my $0.02 worth.

1) What is the official, complete name of the binaries group you
reference above?
2) Is said binary group carried by 'eternal-september'? (Been using them
since AT&T unceremoniously dumped Usenet)
3) If eternal-september is not, what (free) Usenet provider would have
the binary group?
Thanks in advance!

The movie 'Deliverance' isn't a documentary!
Two bands seem plausible to me. Notice that the RF coil adjacent to the
switch has three separate windings which suggests to me either two bands
or a regenerative detector. If we could see the antenna coil,
presumably located directly above the switch on top of the chassis, it
would provide additional information. Most of these 4 tube TRF chassis
that I have seen use some sort of plate detector circuit, so it seems
unlikely that the third coil winding would be part of a regenerative
detector circuit.
What purpose would a "local/distance" switch serve in a radio like this
one? The volume control in most of these 4 tube TRF circuits varies the
bias of the RF amplifier tube via the cathode circuit and also shunts
the antenna, which would seem to eliminate any possible need for a
"local/distance" switch.

Michael,
First, thanks for the response -- but proving again that no good deed
goes unpunished. <grin> See below.
When I clicked on your link above, sure enough, it asked me if I wanted
to subscribe. I clicked 'yes' and then it said 'address not found'.
I am using Thunderbird as a news reader and then went to the Thunderbird
section called 'Managing Newsgroup Subscriptions'. I then clicked
'refresh' to make sure I had the latest and greatest list of newsgroups.
After it refreshed the list, I found 'alt.binaries.pictures.xxxxxx, but
none of the "xxxxx's" were 'radio', nothing close, just listed gardens,
motorcycles and orchids.
Is this something I am doing wrong, or is it eternal-september or is it
Thunderbird? If eternal-september, that brings me back to my question of
a free news group provider that -does- carry the group in question.
Thanks again...
I had assumed that "shortwave" meant 'full band' SW rather than the
old police band sitting just atop the standard BCB. Thus assumed the
switch in question was not a bandswitch. Brain fart before
coffee... :)

Speculation on my part, but the design may have been
prone to overload on strong locals when using a long
antenna? Or, the volume control range may have been
too limited on strong signals?

I've yet to see one of those 4-banger TRFs with a local/distant switch.
There probably are some out there but like a previous poster said,
thats what the volume control did in those circuits.
The SW/Police thing is much more common even if the dial doesn't say so.
Usually the switch just shorted out some turns on the BCB coils.
