James Millen Manufacturing Company, Inc.
150 Exchange Street, Malden, Massachusetts (1972)

Founded by J. Millen, W1HRX, a former engineer from National, in May 1938. High quality HAM and professional radio products and parts.

In 1977 the Millen production was broken up and sold to three different companies.

The main Millen line was acquired by Caywood Electronics, Inc., which was started by Mr. R. Wade Caywood who was at one time a Chief Engineer at Millen and later Vice President and General Manager. In 1987 Caywood was purchased by Ralph Jannini, KA1FAA, who added the name James Millen Electronics, a division of Caywood Electronics, Inc. They continue to service the electronic hobbyist and collector looking for original parts as well as any remaining inventory that exists.

A second company was Electronic Instruments & Specialty Corporation (EIS). EIS created a division called the MC Division. With former factory manager Alvar Melin and office and order control manager Angelo Caputo retaining their past positions, the new company was formed under the new president Robert Painter. The name was later changed to Millen Manufacturing Division (Millen Hardware on their webpage) of Beta Labs, Inc. in Stoneham, Massachusetts. This division primarily manufactures some of the original Millen hardware. The division was sold to Custom Metal Products Inc. in Melrose, MA in 1999.

The third company (and the only one to no longer use any reference to the Millen name) is The MuShield Company, Inc. MuShield was originally managed by Mr. Owen Haszard, who was the former Millen shield specialist in Malden. MuShield moved to Goffstown, New Hampshire in 1989. The MuShield found extensive use in early Millen oscilloscopes. The current manufacturer carries on this product tradition by providing magnetic shielding and monitor enclosures designed to eliminate interference caused by EMI.
