Russian fuse Bk-30

[MINENAZ16]

Hello,

I found in my computer pictures from internet but I can't remember the origin.
The two fuzes look similar but on the diagram it's a BK-30 and on the photo I read B 30 (maybe a part of the marking is missing ?).
Does anyone coud help me ? (same fuze ?)
Thanks.

Regards

It looks like a fuze for use on 115mm Flechette projectiles. American fuzes for use on Flechette projectiles have a push button to enable setting, and a scale that reads in meters for how far away from the gun that you want them to open up.

In the leftmost artist's rendering you can see the range scale and what looks like a push button. It also appears that the ogive is knurled to enable gripping it during the setting procedure.

It appears to be the same fuze. It has the same push button and scale and knurling. Flechette fuzes aren't as common as normal impact fuzes. In the U.S. they have a finer pitch thread so they can't be confused with normal Time fuzes and placed on the wrong projectiles.

Picture is corect, nothing missing.Fuze markings on the fuze is B-30. Used in 100mm ussr flechette projectiles. Maybe the same fuze for 115 mm flechette.
