Unusual Projectile to ID

[khanmak]

This rather unusual projectile belongs to a friend who uses it as a doorstop. I've absolutely no idea what it is! Cailbre is approx 60mm. It appears to have x2 driving bands. The top is solid brass and really well machined so suspect a proper component (rather than a later machined addition?). Both parts are empty. The top brass part has a threaded fuse hole. Only mark seems to be an "H" stamped on the steel part lower part



Any ideas anybody?

The general shape and the rotating bands looks very much like a Gruson product. I fthe diamete ris 53mm, I am sure it is, though I have not seen any info on a 2 piece body.

Hi - its a rather odd size the shell body is actually 60mm but the driving bands are this +2/3mm.

Thanks for showing the photos. A friend of mine has one just like that so I'd be interested in some information on that one too.

Aha - its not alone then! Fingers crossed somebody knows what it is then Dave!

I was checking references, and the 57mm Gruson was called a 60mm to separate it from the 53mm round.These, like the 53mm, wee used in fortifications for flank defense .I can not tell if the thing has threads or a force fit between the 2 parts. I f no threads, likely some sort of cannister?

The 57mm Gruson was called a 60mm to separate it from the 53mm.It was used for flank defense in fortifications, With the brass forward part of the projectile, this could be a practice round to save the rifling?

The Brass top is threaded & screws into the lower body. Its very well made. Thanks chaps - looks like its quite unusual then!
