Requesting details for Russian fuze 3GT, for 76.2mm WW1, mine shells.

Does anyone have one in good condition that strips down easy, who can show me how the needle is suspended inside of the inner tube, I presume a T system at its top and pinned through the collar that the tube slides forward through on impact, but detail is what I am after, please. The cutaway drawings I have show all internals but still leave me guessing. Thanks in advance for any help.
 

Hello, at last a reply to my question, thank you for that. I don't seem to be able to view the attachment, but if it is diagrams of the fuze, then I already have three or four. From those, it appears that the top coil spring is in your cutaway fuze, upside down, small diameter end of spring should be at the bottom. The top nose plug is partway unscrewed, so I am hoping that you can take out the inner tube, if that is possible then can I ask you to remove the tube with its collar and take a few good close-up pictures of the junction at the top of the central needle. From what I can see, the top of the needle has a T, the top of that T appears to be dovetail in shape and passes through the collar that surrounds the sliding inner tube. I have a fuze body and a few internals and if I can get enough detail of how that needle is suspended, I would attempt to try and reproduce those parts to make it a more complete unit. All the best from NZ. TED.

Unfortunatly i dont have it myself .
Its from my album about this fuze.
Just wanted to help you with avaible resources that i posess.
I will talk to someone.
 
I dont have exact dimensions , but i have fuze leftovers with needle , i can measure the needle diameter for you
Is it possible for you to take a few close pictures of the needle remains that you have. The detail I am after is how the needle is held at its top, inside that moveable tube. Looking at the photo of the cutaway fuze you included, I'm thinking that the dovetail shaped pin is passed through the outer collar which we can see, and through the chase cut in either side of the tube. The needle could have a fine threaded top that then is screwed into a hole to match in the bottom center of that dovetailed cross pin. It appears from the sectioned drawings that the needle is longer than the side cuts in the tube, it would have to be, to stop the needle being thrown out of alignment on graze, or in other words its point ending up outside of the tube. Thank you for your help, TED, NZ.
