Chinese Fuzes

[ron3350]

I would like to know the model and use of these 2 long Chinese fuses.
Both fuzes are aluminium with steel adjusting rings. 3mm/9tpi threads 59.5mm diameter.

1. Long. Has a white band/nose and is 181.5mm overall and 63.5mm wide.
Symbol - 5 (crossed out) 6. - 484 . Is it a time delay type 6?

2. Shorter graduated 1 - 60. 157mm overall and 63.5mm wide. Same threads as above.
2x symbols - symbol. 1 - 79 484.

I guess 484 is the maker factory and 1979 date.

Looks like there MS 1 MT or their copy of Soviet VM 30

i just got some of the same fuzes,i understand they are type 6 mechanical delay(they have a clockwork inside and would make a good cutaway)
they go on a large rocket but i cant find out which one yet

For the left fuze the first character isn't very clear, but the later seem to be 時-1式. I'm not good with Chinese, but a Chinese speaker, well reader, may be able to help you. However, and according to Google translate, the characters mean '?? Time 1 Type', so its probably an 'MS-1S'.

As to what they are, the left would seem to be based on the (almost the same) Soviet/Russian TM-16 or VM-16 series mechanical time (MT) fuzes. The former is normally used with artillery (naval or coastal) dispenser projectiles and would have a igniferous (black power) output. The latter would be used with high explosive artillery (naval or coastal) projectiles and have a detonative (tetryl) output.

The one on the right may be based on the Soviet/Russian TM-120 or the GDT-90, but with a revised nose and an explosive output assembly. Both are normally used with dispenser artillery rockets and have an igniferous output.

Nice to see some replies as I had little knowledge on them. Thanks to all.

The one on the left is '海时-1式'. '海' means sea, so it's for navy ammunitions. The one on the right is '时-5'. Both are mechanical delay. I think I have more detailed files on both, but they're at home. Reach you later when Im home.

The one on the left, namely '海时-1式', is shown in fig 1. I dont have the exploded view of it. It's used on navy 100mm and 130mm airburst HE rounds, as shown in fig 2 (its title is inaccurate, there's no evidence the weapon is designated type 56).
The one on the right however, the files are much more detailed. According to the files, it's a Chinese version of the Russian BM-30Л fuze, used on 85mm and 100mm airburst HE rounds.

I think the right fuze is a modified 时-5 with a longer cap, so 时-6.

You are right about this one. Ive checked again, and find a pic from one of the sellers:

from left to right are 时-5，海时-1 and 时-6. So ron's 2nd one should be 时-6 instead. Unfortunately I dont have any files of it.
It's said that BM-30Л, which is the origin of 时-5, is a soviet rip-off of the wehrmacht 88mm flak time delay fuze.
