Museums are an opportunity to get acquainted with history, to immerse yourself in the reality of other chronological frameworks. Thus, with the help of exhibits and elite writing from you will be able to reproduce the cultural stratum. The following is a press release to the Center for Military History newsletter

A three year waiting period finally paid off for the Signal Corps Museum. It all started off as a casual conversation between a museum volunteer Mr. Cliff Manasco and Mr. David Bock a Civil War Signal Corps history enthusiast. On April 30th two, fully functional, Civil War era, reproduction Beardslee Electromagnetic Telegraphs were delivered. The museum has a rare original of one of the machines. Parts are missing and naturally couldn't be used even if it was complete.

Mr. Mike Rodgers, exhibits designer, took many photos of the original Beardslee for Mr. Bock and his partners Mr. David Harbin and Mr. Ted Wagner to get started making the Beardslees. This was no small undertaking. They made six Beardslees in all. The outward appearance of the machines are exactly like the original but that is where the similarities ends. The insides of the machines are full of electronics. With no schematics to go by Mr. Bock and his partners had to figure out how to make the machines work like the original. Fortunately Mr. Bock is an electronics designer. After many failures, successes and field trials the machines performed as the original would. They even built in electronic "faults" which were characteristic of the original. Mr. Bock and partners absorbed the cost for both machines estimated to be worth $15,000.00 EACH !!

The Beardslees will be used as an educational tool for all groups visiting the museum as well as the museum's "living history" program. The educational value is priceless as are the machines. For more information on the Beardslee go to .
