The No.36 was the most common British grenade of ww2 but already found its form in 1917. It stayed into service well into the 1970's.
Its body was made of cast iron, its components were made of steel, brass or zinc.
The detonator had to be inserted before use after removing the base plug.
Red crosses on the body indicate that it has a filling suitable for tropical use (humidity) and the coloured band over the middle tells what filling was used.

Mills grenades are known in many different casts, check Dave Sampson's site, he's got a great collection!

Mills grenades have been manufactured by many different factories.
To see some different markings on the bodies,

The det box on the right was the one that carried the "live" fuze-assemblies.


Shown below is a complete box as issued during ww2. It carried 12 genades, a tin with 12 detonator assemblies and a key to unscrew the baseplugs.

NZ crate :

This is a New Zealand manufactured box, made by Ford.
The markings on this example were changed after re-issue and some text was deleted.

The (drill) detonator tin shown below is property of
Bart, New Zealand.
These inert assemblies carry no explosive compounds. The detonator is an empty aluminium tube.


Shown below (left) are the tools to fit the spring and strikers onto practice grenades, and to take the grenade to parts.

The right photo shows what happens when you go nuts with a grinder-tool.

Right picture : Two different casts of the No36 Practice grenade.
Hence the strengthened lugs on the left (Mk2) model.
It is supposed to have a baseplug with a larger threaded hole to fit the laucher-disc, when used as a rifle grenade.
These improvements were needed as trainer-grenades got easily damaged by multiple use.

Considering the story that the Mk2 version was strengthened for multiple practice use , it is very strange that in the last year, I found two No36 Mk2's on a WW2 battlefield. Both "red crosses" marked and filled.
Unfortunately both of these grenades were found without their baseplugs.
Why were these used as live ones?
