Was this used as part of the "omni" navigation network in use back in
Had an "omni" beacon with in 100 yds of my boat in the 1980 time

ARN-6 was a fairly simple radio receiver broadcast band and below IIRC. The

ual Omni Range)
The nav unit was the ARN 14 for the vhf vor system. The military
system was the Tacan system also included in most navigation ground
stations. This system gave distance as well as bearing information.
The vor system also had a Distance Measuring Equipment DME which for
civilian use gave the distance to the station from the aircraft.
The ARN 6 was a low frequency direction finding unit. It would home in
on any radio broadcast signal. The antenna had a goniometer which was
a rotation ferite antenna and a long wire sense antenna. the goniometer
was servoed with information from the two detected signals. The ferite
antenna would seek a null signal and the indicator in the panel would
indicate the direction of the station.
Posting from my desk top PC in the living room,
2995, first thought is oil drain plug with magnet.
Second thought is burner orifice from an ocean
2996, when misbehaved carpentry students are made
to sit in the corner, they must wear this.
2997, prototype of the dirigible Hindenberg. This
lead filled model was less successful than the
2998, possibly an early ending machine, but for
what products, no clue.
2999, cracking walnuts, and crimping wire lugs.
3000, part of a carpenter's measuring device.
The offset wobbler and shimmy shaft are missing.
Good one, Rob. You got me on all of them. No clue.
The usual posting from Rec.crafts.metalworking -- where do the
rest of you post from (which newsgroup, not where are you sitting. :-)
2995) Looks to me like a fuseable plug -- in a boiler or something
similar -- designed for the pink stuff to melt and blow out when
the temperature and pressure get too high.
2996) For supporting something printed on paper -- not quite stiff
enough to be cardboard. Perhaps music at an organ, or something
similar - except it is not clear how it mounts to what from just
the single view.
2997) Streamlined housing for an antenna (fairly high frequency) on
an aircraft. Not metal -- probably some fiberglass or plastic
selected to be transparent to the frequency of RF involved.
2998) It vaguely looks like a Coca-Cola bottle vending machine,
except that I would expect the output side to be on the bottom,
not the top.
But I don't see a power cord to keep the bottles cold. (Perhaps
a lack of the proper angle of view. :-)
At least some kind of vending machine, with the lever, the coin
slot, and the coin return slot on the right.
Does the presence of the fire extinguisher have any
And it seems to be in a church, based on what looks like a
stained-glass window behind it. :-)
2999) Different possibilities:
1 -- stapler and staple remover
2 -- Oil can opener and pouring spout.
3 -- something which I have missed totally.
3000) Looks like some kind of woodworking tool -- *made* by a good
woodworker. But what its precise function is I'm not sure.
Now to post and then see what others have suggested.
I'm guessing it was coiled up on the back, but I didn't take the time to look
I took the photo in a second-hand store, there was lots of stuff piled
everywhere, so there isn't any real significance. BTW, I like the interior shot
that I found on the web better than the external one and probably would have
used it as the puzzle had I found it before I posted yesterday morning.
Thanks, that's a good photo, I just added a link to it on the site.
