Unknown Projectile

[jvollenberg]

I have no idea on this one. I think it is German, just by the look, but could be wrong.

Diameter: 105-MM or 75-MM (we must have messed up on the measurements at the time)
Length: 478-MM

No info on this rocket assisted shell but with this length it's not a 75mm.
General shape matches with German 10.5cm Gr19.

Judging by the length , shape & the two grooved driving bands , I suspect this Rocket assisted projectile is for the s. 10,5cm Kanone 35 (t)

The thread could very well be 48mm wide & not M50 x 3 , however that wouldn’t necessarily be the deciding factor in this case. But would be nice to know.

Attached some images to show what I mean. One is a close-up of the driving bands , the other the thread & then the German documents on the 10,5cm Granate 35 (t) variants. I’m unable to read the length of the projectiles mentioned properly but if I read it correctly , it says something like 540mm including fuze. So the length is definitely not far off , if any.

Skoda developed more things like this so it would make sense.

Now all that’s left is to find a document in which this is mentioned.

Not same bands on Gr35.
I found one (total length 544mm, without fuze and adapter 494mm).

don’t think I’ve ever seen one before. Only the cases. Very nice! Do u have images of the complete projectile?

Found in France, so captured shell

I just wonder, why is the rear part of this rocket assisted projectile so thick walled and so complicated in construction... :tinysmile_cry_t2:

This is an interesting round. It looks like the internals are similar to the Nebelwerfer, just inside of a projectile body.

Skoda designs are often complicated
IMHO there had to be a base fuze (impact), because I cannot see any means of initiating it thru the motor chamber.

I suspected, the HE charge could be placed in the rearmost compartment, fuze in the middle compartment, then engine and a time fuze igniting the engine in the nose.
This small thread at the base of the combustion chamber is also a little bit intriguing - it was probably fixing an igniter and/or an insert or a grid holding the propellant grain(s) in place.
