Help ID fuse in Russian 122mm HE shell

[FCSA-UK]

Hi,

Looking to restore a relic condition 122mm Russian HE shell, the fuse is in a bad way so thinking of just replacing with something less corroded.

Does anyone know the fuse type that I should be looking for? (I have a V-429 and the fuse in the photos below is shorter than the V-429). The top section as seen removed below is 14.24mm tall - excluding top and bottom threads.

Many thanks

You might want to look for this type...

Hi FSCA-UK
Can you provide a photo of the entire projectile with the adapter screwed on and if possible, maybe measure the height of the entire projectile and the height of the separate adapter for the fuse?
I would appreciate that
Or who would like to join in?

Hi FCSA-UK,
As Akon says, looks like the upper part of the KTM-1,

It is a KTM-2 and the shell is most likely a 122mm D-462 (53-Д-462) smoke shell. It must have a long burster tube screwed into the fuze well.

We have a sample - original photo - I would say that it does not fit..when I compare it with the OF-462A version or the D-462 version.Namely, the D-462 version has an internal case for the charge and it would be visible and it is not there.The OF-462A version - here it contradicts the height of the case ...(estimate) until we have a photo and measurements..
That ammo sample case is definitely inferior.
Interesting Russian sources state that until 1935 there was also a version of the ОФ-462Л (OF-462L) available, about which I know absolutely nothing...By the way, the sources state that the previously produced O-462А shell was later re-designated OF-462A.

I'm waiting for colleague to measure it and take a picture - for now I'm just guessing..

Hi LEAFLET
The fuse body on the FCSA-UK sample is one-piece, you provide a photo and a cross-section of the KTM-1, it is definitely two-piece (fuse body). I think it is not identical Let's look ...

I got confused thinking the disassembled upper part of the fuze being the whole fuze. The portion of the upper thread is similar to the KTM-2’s thread. So i might have been wrong stating it is KTM-2, but
it’s still one KTM version, the only difference between them is the thread diameter.

One of the lesser known and non-series produced versions of the KTM fuse is the KTM-14 (developed in 1942)
