In 1962 Mitre Master Products Co. of San Fernando began manufacturing what was one of the very first portable miter saws. Their saw was patented that year by Leo M. Schwartz of San Fernando.

By 1964 the address printed on the labels affixed to these saws was B & E Products, Inc., 2033 Grandville Avenue Los Angeles 25, California.

A 1971 patent for improvements to the saw was granted to Ace C. Boultinghouse and assigned to B & E. Products, Inc. and Ralph Sadler Rosen.

By 1971 the address of the company producing these saws had changed again, this time to 3540 Wilshire Blvd., Los Angeles, CA. 90010

And by 1979 the address had once again changed, this time to 3103 S LaCienega Blvd, Los Angeles 90016.

Successive model numbers for these saws include 62A, 64A, 66A, and the corresponding addresses and/or company names suggest that these model numbers as well as the last two digits of the serial number correspond to the year in which those saws were manufactured. Into the early seventies the model number was changed to simply A and then B. Those versions featured a larger induction motor and an aluminum extrusion for the table and fence.
