‘Lamps, Operator’  WftW Pamphlet No. 2.

About this WftW Pamphlet No. 2 (Previously ‘Overview’).

Small operator lamps were issued with most British (and Commonwealth) Army vehicle and ground radio stations, normally powered directly from a socket fitted on the front panel of the set. This Pamphlet shows the presently known versions and variations.

It was stimulated by Chris Bisaillion VE3CBK who asked me to identify a couple of early ‘Lamps Operator’ from his collection. Remembering that these particular lamps were in my modest collection, and in spite of the bitter coldness in the garage where I had these stored, I managed to locate the box and thus able to give a positive reply. Seeing all the variations in the box and knowing that Chris had also a good selection in his collection, we decided to compile a small illustrated list, just for our personal use. This became the main core of this Pamphlet No. 2.

Eventually others contributed to the list, and at that stage I decided to compile this WftW Pamphlet for the benefit of anyone interested in this subject. We are grateful to the contribution of photos, scans and support from Tony Bell, Australia and Mike Willenbroek, Holland.

Newly found material may be included in later published versions of this publication. This will be announced in the What’s New’ page.
