Notes about production
1. Molds with and without the MR exist so the MR was added after
the mold was used in a particular year since there is no sign of a blot
out. The dash between HEMINGRAY and 42 has been thickened in the MR
20C mold.
2. Four molds have been identified: 20C, 33C, 36A, 52A.
3. Two different years of production exist:
How many exist?
About 10-30 of these are known to exist. John Scherzinger reported
in September 2003 finding two of them in a Wisconsin pile (mold 52A and 36A).
One was found in Kentucky. Back in the 1970's about half a dozen
were found in a flea market in New Jersey. There is also a report
of about 20 of them coming from a central Indiana collector who found them
on a phone line, didn't think they were worth much and crackled them to sell
them at a London, OH insulator show.
What does the MR stand for?
No one knows what the MR stands for at this point. There is much
speculation, however. The main thread is that it is an abbreviation
for something. Possible names that it could be an abbreviation for
include:
Military Requisition |
The date codes of the MR indicate they were made
about 1939 which is pretty late for any interest in these by the military.
No other insulator has turned up with the letters MR on it even though
the military purchased CD 113 Hemingray-12s and CD 160 Hemingray-14s as well
as IN-56s. |
Milwaukee Road |
Although used extensively by collectors, few items
were marked Milwaukee Road but where marked with the full name of the railroad:
C.M.St.P.& P. R.R. for the Chicago, Milwaukee, St. Paul & Pacific.
The Milwaukee Road may have been in receivership during the time these
insulators were made. |
M? Railroad |
Examples of railroad names include: Monongahela
Railroad, or Madison Railroad (a southern Indiana railroad that did not exist
in 1936).Some other railroad line that began with an M is unlikely given
that the insulators have been found scattered throughout the Northeast quarter
of the United States including New Jersey, Southern Indiana, and Northern
Wisconsin. It's unlikely a railroad line services all these areas.
The Wisconsin find was from a pile created from a phone line, not a
railroad line. |
Mold R? |
The R could stand for Replacement, Revision or Rework |
Muncie Reunion |
The M could stand for Muncie, the city of the headquarters
of Hemingray. Maybe R stood for Reunion. Many cities celebrate
homecomings and local companies make mementos of it. Square-D made
little paperweights for some Peru, IN event like this. |
Madison Railroad |
This Southern Indiana railroad did not exist in
1936. |
The Initials of an Employee |
There are several examples from the Kerr/Armstrong/Whitall-Tatum
company of bottles being made with an employees name on them so why not a
retiring worker getting his or her initials on an insulator at the Hemingray
plant? As of Sept. 2003, no employee has been found that fits this
scenario and it doesn't make sense that four molds would be used to commemorate
such a retirement when one mold would be enough. Also the molds used
deal with two different years. |
Map Reference |
Perhaps the MR letters are large so they could be
read from the ground and served to mark which pole on the map they were standing
next to. |
