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.
