to Identify an Elkhart 8D
Conn 8D with a six digit serial number and
no letter prefix is not necessarily an Elkhart
8D. When Conn moved to Abilene, Texas they
did make horns with six digit serial numbers
that drastically overlap the Elkhart numbers.
first thing to look for is the bell engraving.
If it says "C.G. Conn, Ltd., USA" with
no reference to Elkhart Indiana, it is an Abilene
pre-letter series Elkhart 8D's had a mechanical linkage on the change valve.
If yours has a string linkage, look for signs that the old linkage has switched.
In order to make this modification, the stop plate has been rotated 90 degrees.
You should be able to see where it was originally and also, the old screw holes
that held the stop plate in its original position will be plugged and visible.
If this is not evident, then chances are you have an Abilene horn.
horns have 2nd valve pull rings that are as thick as the ones on the new Cleveland
horns. Elkhart horns, with the exception of the "N" series have rather
thin pull rings.
positive way to tell an Abilene 8D from an Elkhart 8D is to remove a rotary
valve and measure the rotor with either a micrometer or a set of dial calipers.
The rotor of an Elkhart 8D is tapered. An Abilene 8D has cylindrical rotors.
The cylindrical rotors were one of the biggest design flaws in the Abilene
