Lincoln 1920's vintage
type
Learadio Type C Headphones low impedance, probably 1950's or so
Notes:
Leich: 2000 ohm early 1920's middle of the road to cheap headphones,
nothing special but fairly uncommon.
Lincoln: Two early versions, one with the lightning bolts appears to
le late 1920's, the one with Abe on the housings looks like late 30's.
There was also a Lincoln headset by Allied Radio in the 1950's to 60's,
black plastic cans, cheap setsl. The earlier ones are economy grade but
mine work well with fair to good sensitivity.
M, MESCO: Manhattan Electric Supply Company, made these with the M
and lightning bolt on the back mid 1920's, also made the Red Seal
headphones
of identical construction. The headband was a stiff double metal
headband,
phones were middle to low end in quality and middle of the road for
sensitivity.
The earcaps tended to crack with age.
METRO: There was a 1920's crystal radio by the same
company, both are fairly uncommon. These are middle of the road quality
and sensitivity.
MicoPhone: By Meissner, mid 1920's, these are quite rare,
this is the only pair I have ever seen, very nicely made with great
sensitivity
and tone.
Moulton Juniors: Fairly uncommon 1920's and rather cehaply
made with one central coil, never seen a pair of Moulton Seniors.
Murdock: The Murdock 55 was a very early circa 1914-1920 wireless era
headset with the ball and socket connections. Good quality but not too
expensive at the time, quite expensive now since they were from the
pre-broadcast
radio days and not many are around. The 56 model was made from about
1921
replacing the 55 model, and came in 2000 or 3000 ohm impedances. The
56's
are quite common but the 55's are rare.
Meteor: I see these for aution online a lot, they seemed to hold up
well over the years for a low end headphones from the late 1920's to
1930's..
New-Ton: Don't know much about these, look like midgrade consumer
headphones,
work well.
NERCO: These are bulky and not very sensitive. Look like late 20's
to early 1930's vintage
New Yorker: A model of cheap headphones later 20's to early 30's though
after I resoldered the wires inside had OK sensitivity.
NRI: Look like they were made by Cannon for NRI, economy consumer grade
phones late 30's to 40's.
Northern Electric: The Canadian version of Western Electric, are high
quality for telephone or radio applications 1920's.
