British No.720 vaned fuze 2 inch rocket

[Rrickoshae]

Good morning, please see the attached photos of a No.720 MkIV rocket fuze. The stamping reads 720 MkIV N Roneo 42 Lot 54 which I take to mean that it was manufactured in 1942 against a naval contract. But according to Len Webbs paper on numbered fuzes, the 720 was not introduced until 1944. Would pre production examples have been made 2 years before entering service?

Also does anyone have a photo or drawing of the naval 2 inch AA rocket which I believe were mounted in frames similar to Z battery rockets on the side of ships turrets?

many thanks Dave

How about this?

Dave,
One of the design drawings for the 720 fuze is dated 24th Sept 1941.

I wouldn't take the dates in that document as 'Gospel', as there appear to be a number of 'errors'. It is possible that they are 'typos' or that the store was in service and there was a delay before its introduction was announced.

yes, I had rather thought that was the case Tim, thank you
