1 pounder incendiary projectile

[SG500]

Attached some photos of what appears to be a fired 1 pounder incendiary projectile.
The side vents are clearly visible, at an angle as expected.
The base is missing.
Is anyone able to post photos of what the base would look like - photos or drawing please?
Can anyone interpret the stampings please?
Thanks.
Dave.

There seems to be two versions of projectile, the full length French Mle 92 and a shortened version.
The full length has the same exposure of a standard British 1pr.
The only reason I can think of for the shorter one is use in a different gun, the MKlll light Maxim which uses a shorter
projectile. These examples are not mine. The idea seems to be the same as used in the 40mm Crayford projectile and the French
Mle 1892 projectile with the fuze removed and base altered is ideal. One wonders why nothing seems to have come of this ?
A similar profile is used with the 1pr Incendiary phosphorous projectile, example not mine.

Hi,
The French Navy's Model 1890 "rupture shell" was closed by a base plug that could not receive a base fuse.

It was replaced by the Model 1892 "rupture shell" with base fuse.

A few years ago, I found this unusual-looking shell at a flea market, used as a plumb line(!). After unscrewing the base cap, I noticed that a very hard, gray matter filled it.

I found that this material (56 grams) burned with a bright yellow-green glow.
It would therefore be (I do not have an official document from the period) a French model 1890 shell modified by the drilling of 2 oblique vents in order to be used as a 1 pound incendiary anti-balloon projectile by the English army.

So...how did you manage to remove this stuff? Just dig it out? Couldn't that be unstable and dangerous? Just curious...

I had thought that it was a Mle 1892 base that had been cut shorter removing the fuze threads and pocket.
I have Mle 1888 which takes a fuze but has thin Hotchkiss type threads on the base plug.
I have not heard of this 1890 type until now ! I presume it was a practice shot or a sort of solid shot in
service then with the 1888s still onhand ?
A very interesting find for you ! Too bad there seems to be no official information to be found.

I must note one thing, your base is marked F98 this means that it did have a fuze, the Mle1886 as modified in 1898
as a safety measure. So I think it has a shortened base plug not the 1890 practice shot type.
I attach the fuze modification, the unmodified fuze came out of a Mle 1892 the base which was not marked F98,
the modified fuze came out of a Mle 1892 whose base was marked F98. The idea was to prevent the parts from shifting
or being able to so that the projectile could not be set off if dropped. This had apperantly happened in service.
