Help indentifying WW1 Somme relic...

[specialed]

hi, could anyone tell me what this item might be? picked up 20 odd years ago in france... thanks!

Looks like the inner guide bogey wheel to a tank or half track

thanks dave, but i don't think that's likely. the small round indentation on the base is brass, and looks like some kind of firing pin, and there are evenly spaced holes around the side, which you can just make out, if any of that helps...

[specialed]

any ideas, anyone?

It's been suggested that: It is the base of a 4" Stokes (chemical mortar) round. This is the later type and this part contained the propellant charge, gases were vented through the holes. The original design from 1915 had a tubular tail with a cartridge like the 3". Any comments?
