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.
