Always fuze No.247, how many types?

[lexpev]

How many No.247-variants are there?

Maybe someone can add up to a list of six so far.
No.30gren.fuze, No.54gren.fuze, shortened tape/red cap and the MkIII that was factory loaded through the base.
Seven types if you count the (Bomb) Tail fuze No.854 too...

I have two different types here, but one of them I have never seen in any documentation.
Left one on photo is the common type.
Why does the right one in the photo below have small snout?
Who has this too?

Lexpev i have added some more pics of the 247 in documents,i have seen a lot of the 247 with the snout bit ,whilst clearing an old demolitions area ,i did notice they were different but never looked into it ,it would be interesting to find out if they were for a specific grenade or just a manufacturers variation

Hi Spotter,

The documents look good.
I got that 247 from a relic No.69.
It's all I know...
