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.
