Proximity fuze L7 AMK1.
- Thread starter ron3350
- Start date
This was one of the earliest British CVT fuzes and was declared obsolete by 1962 (W.O.L.C. 9943 refers).
This particular fuze has mixed two systems. The introduction of the L series did away with the mark system and introduced, say, L7A fuze followed by 1, 2, 3 etc indicating model changes. The L7A for some reason still had a mark number after the A.
I remember it from those days but I cannot find any publication old enough to identify its use, but very likely 25 Pr or the Italian 105mm gun which came in around 1960.
I have just found that both the L7A and the T97 were being used in Cartridges 3.7" AA Mks 1 - 3 Gun HE and Practice in mid 1960.

The hybrid system of 'L and Mark' is not unique to the L7, though it is interesting to see this fuze is LnA Mk.
In 1952, the Organization and Weapons Policy Committee approved the adoption of a new system of nomenclature for all future Land Service weapons and ammunition, generally based on and similar to the American system. That said, the "Revised System of Nomenclature for New British Weapons and Ammunition" wasn't introduced until 1954.
As can be seen from the L10 fuze it was manufactured in 1952 and in theory introduced after after the L1 and L7. So, is it possible that the "L and Mark" was the first new system, subsequently refined into the "L and A" system?
