Can anyone tell me anything about a British L85 series of projectile fuze? All I have is the nomenclature and was wondering if someone could provide some infomration and maybe pictures?

L85 series projectile Fuze
- Thread starter jvollenberg
- Start date
From the info i have from 2004 Its a superquick fuze with optional delay ,used on 105 and 155mm projectiles,
The differences between the L85A1 and L85A2 are the optional delay is increased from 0.02-0.03 seconds, and several components from the initiating train were changed from brass to aluminium or plated with nickel, the gaine was also changed from the L7 to the L7A2 which has an anti roll setback to prevent arming if the gaine is rolled
attached drawing shows the L85A2

Joe,
It is more than likely one of yours. For a period after the Second World War we (the British) were using American fuzes - some of which were manufactured under licence in the UK. The fuzes retained their American designation. This fuze looks very similar to the M51 (I'm not totally conversant with American fuzes as yet) so this could be a British variation and/or they decided to drop the American designation and make it a 'L' series fuze.

Am I wrong in thinking it looks similar to the M557 fuze? That one could arm if rolled in excess of 6 mph.

IIRC L85 was introduced as a lower cost alternative to the L32. The latter was introduced with 105mm Abbot.
I am looking for some information on the L7A2 fuze booster ... I have them being made by Italy. Borletti specifically as the manufacturer. I was wondering if the UK made these and if someone had a close up picture of the booster and the LOT code on it?

Actually ... I have the entire fuze being made in Italy. Does anyone have a close up of the fuze LOT code as well?

I think this is a M-572 nose fuze, as the nose piece is filled with expoxy resign. This fuze was used on high speed shells as the 175mm HE.

This is the brochure I received on the fuze from an Italian Company.
