unknown fuze / impact mechanism

[Nabob]

Hello,
I am looking for ID on this item.
It seems to be a fuze or a part of a fuze.
Length aprox. 38 mm
Max. diameter 26,9 mm
Max thread diameter 24,35 mm

Do I read it correctly the markings as 321 and 85?
The ring seems to be lead.
There are two angled holes in the body on the opposing sides.

Thanks, Bob.

Thank you!
The lead strip must have been added for better function on impact.

Hi Bob@ gentleman
The shape of the lead tape suggests something, so I see two possibilities:
a) to materialize the impact mechanism strung on the part with a smaller diameter (to increase the sensitivity of the igniter).
b) placed in the space between the impact mechanism and the needle for the function of deformation safety. During the fall, it will ensure that the distance of the trigger from the needle is maintained and will not allow the normal fall of the shell during storage to overcome the resistance of the lead tape and thereby move the trigger on the needle.
What do you think about it ?

Thanks for the link AKON,
judging from the spacing and length of the 4 prong needle, option b) is not possible.
I would go with option a) especially with lower velocities on longer ranges the increased mass of the inertia driven piece would help to cut the shear wire and still have enough energy to initiate the fuze.

Díky za odkaz R....,
podle množství místa a délky čtyřhroté jehly je možnost b) nereálná.
Přikláním se k a). Větší hmota setrvačnostní úderky pomůže při nižších rychlostech dopadu na větších vzdálenostech k přestřižení drátku a dostatkem energie pro iniciaci roznětky.
