Please Help. 4"in Mk 16 & 21 Gun "Gauge Testing" and "Fuze Setting Machine" What is?

[Andy Naude]

Have just seen this on a 4 inch Mk. 16 and 21 Gun case.

GAUGE TESTING
FUZE SETTING MACHINE>

What is this? Is it some sort of armourers drill?

Received this reply from an old friend:

Yes, exactly as I expected. This is not a Drill Round for gunners to play with.

This would have been used by the Weapons Electrical Artificer (Weapons Electrician) and Ordnance Artificer (Armament Fitter) to set-up and test the fuse setting machine that the round is fed into seconds before loading and firing either in surface or AA mode. It would probably have been kept in a wooden "storage and transportation" box and handled carefully as it is a piece of "test equipment" and therefore to be treated as an instrument.The stand does not look original to me.


The fuze setting machine would have been on a ship with powered mountings to make the best use of the radar information, the Transmitting Station fire-control computer and the ability of the mounting to track fast moving targets.

Does any one have a photo of a manual fuze setter?
