The chimes in question were made by the Fox factory in England. Everett Hilty in Colordo had one of the first sets that he used with his college ringers. The first time most of us (at least in the west) saw or heard chimes was at the AGHER seminar at the Womens College in Denver in the late 80's. His college choir rang the opening concert of the seminar and used them in the concert. It was at the same seminar that people started talking about six-in-hand and the two ringers that had come up with the technique were in D3enver to share their technique with us. Getting back to the chimes, Schulmerich imported the chimes from Fox in England and acted as the U.S. distributor for them. By the time the Fox factory in England went out of business, Schulmerich had started development on their own brand of chimes.
I understand these chimes were called Handchimes and distributed by the Handchime Co. of England, though made by Fox. They eventually went out of business and Schulmerich bought and sold the remaining stock. Fascinating instruments! They had a hole in it that you could create either a muted kind of sound or a vibrato - like touching the bass of the tines of Malmark Choirchimes or the current Schulmerich chimes.
By the way, the two ringers that taught 6-in-hand at the AGEHR Directors Seminar in Denver (Denver Women's College) was my ringer, Marty Brent (see "Marty's Six-In-Hand Ring" in Overtones compendium), who invented the technique, and myself. We closed the class ringing "My Grandfather's Clock" out of the Scott Perry book - 12 bells, 2 ringers. Great fun!
