That is a VERY desirable item!!!

The Russians did some similar rounds that were intended to be used against observation balloons. I've seen them with similar unfolding jaws and with cables that would unwrap from around the body. both have been previously posted on other threads.

Russian anti-balloon projos

I love the lost history pieces, the hard to study esoterica that few realise existed. In this line I'd like to show a couple of my favorite early Russian projectiles, both 76.2mm anti-balloon rounds. Each used the standard Russian powder-train time fuze, one to release four snagging blades, the...

heres my take on drawing for 3d. Projo is 9in tall. 2.98in body OD and 3.085in DB OD

There are two confirmed examples of this projectile in NZ.
Given the limited elevation and short range of this calibre I think it unlikely to be anti-balloon and more likely to be for attack on wire defences.
the outer projectile is the same as the shrapnel projectile and one might assume old shrapnel being emptied of shot and resin and reloaded with the inner contraption. Even though extant examples have outer shells dated in the 1890s it is postulated that the inner workings date from WWI.

Did you happen to create a 3D .STL file(s) for the inner Grapnel part?

Made my own. Ran out of brass paint for the fuze. Looks better on a video

Yes

With the generous support of Dronic69 the model has been modified to ensure it will fit inside a standard 15pr Shrapnel shell

Great job!
Thank you Sir for your persistence!
Can't wait to "test" it - you don't happen to have a 3D full size 15pdr gun I can borrow?

I'm sure you have seen these images, but repost for others.

yes, those images of the the example held by NZDF in the EOD Trg Aid Museum. There is another in private hands, also in NZ

Thanks for that, however, my painting and stencilling days are well and truly over! Spend far too much time as as a teenager focusing on ordnance, when I could have been out chasing "other" things in life....................
