Letter Dated Dec 1965

This is quite an interesting letter from 1965 addressed to the Editor of "Motor" magazine, it regards the range of Bob Soper Hi-Torque products that are available and invites "The Motor" to come & test the products. It also confirms Bob Soper’s attendance at the 1965 racing car show. Thanks to Angelo Bortesi for sending me copies of this very interesting document.

A second very interesting enclosure. This one refers to the Hi_torque range of Blower drives for the Shorrock range of Superchargers. Bob Soper was the Yorkshire agent for these highly successful superchargers throughout the 1960's..
