    TimG and Bonnex - thanks for info - interesting! so the L3A1 I have is a trials item and not 'production' version? so was the PRAC type trialled at same time as the 'live' L2A1 and introduced together? I thought experimental ordnance was either painted purple or had purple stripe, unless there is a different meaning between 'trials' and 'experimental'?

    if mine is trials, I'd like a 'regular' L3A1 (not sure if any changes were made, other than of course dropping trials markings?) too if anyone has one?
    always looking for inert baton rounds and accessories - please message me if you have any for sale/trade.

    Yours is a survivor of the trials programme, and is special for that, but it was not the actual subject of the trials that I mentioned. The HE (L2A1) and the live L25 Fuze were the items under trial and the Inert (L3A1) was used to provide a carrier for the live fuze (and sometimes the projection adapter). Typically a combination of an Inert (L3A1) and a live Fuze (L25) was used to test a safety feature of the Fuze, for example one test required grenades fitted for rifle projection to be fired, with the safety pin in place, at short range at a thick steel plate. In a sense the Inert (L3A1) was a piece of expendable trials apparatus. I would expect the Inert (L3A1) grenades to have been taken from stock and the additional stencilling (Requisition number etc.) put on as a Depot task. Because they were not the actual subjects of the trial I would not expect to see any purple paint.

    The HE (L2A1) grenades for the trial were taken from production. Stencilling would include the requisition number and 'ITEM D'. It is possible that these grenades (and the fuzes) would have a purple stripe but I would be guided by AE501 on this matter.

    Sorry this is more waffle than useful info.

    thanks for the info Bonnex - so these trials were after each of these items had been adopted by the Army? would be interested in more about the the development/service of the L2 series and related training grenades; also, interested in the end of service of the Mills which was being replaced...

    Yes, these particular trials were carried out after the grenade and accessories were approved for service. The grenade (or rather the Fuze L25A2) had functioned prematurely three times during a trial at Pendine in 1965 and the OB 40404 trial that your grenade featured in was concerned with evaluating modifications that had been proposed by RARDE to eliminate the premature functioning and other failures.

    You will likely know that the HE grenade (L2A1) had a chequered history. The UK Armament Design Department had been experimenting with wire-wound hand and rifle grenades during WW2 but the end of the war was quickly followed by financial cuts which ended of many munitions development programmes. Grenade projects were effectively trashed and work on wire-wound, rocket-assisted and magnesium bodied grenades ceased and the files and models destroyed. During the 1950s War Office Policy Statement No 82 specified the characteristics required of a fragmentation hand grenade; it was a return to the work of the wire-wound team. Fortunately the specification was largely met by the US M26 and it was proposed to acquire supplies from the USA. However, and this is the point where it goes wrong, the British engineers and scientists would not countenance an un-shuttered lead azide detonator being incorporated in a fuze which was assembled to the grenade body during production; the M26 was shipped with the fuze fitted. RARDE designed the X5 grenade and fuze (X40) with associated packing that would ensure the necessary separation to avoid mishaps in storage or transportation. Unfortunately when assembled together the detonator in the fuze occasionally failed to detonate the grenade body. Thus there began a 50 year or so struggle to produce a reliable fuze and grenade combination which was finally achieved in 2002 with the introduction of the Grenade Hand HE L109A1!
