Fuze ID please

Thanks Hazord. I thought those fuzes were made all of Alloy not brass - do you have a picture of an actual fuze in brass?

Burney,
I haven't ever seen the whole fuze in Brass, just the part that you have. I have two pieces just like yours in brass. The majority are the zinc alloy body with aluminum button on the tip, but I also have a fuze or two where the main body parts are black plastic.
The tip part that you have is threaded at theback, so it can be screwed into any of the lower bodies.

Hello John & Burney,
Your brass mortar fuze head belongs to the U.S. Fuze, PD, M82 which was used only on the 60mm M302 W/P shell. The brass head was used for identification of the M82 fuze verses the M52 series for this reason. The M82 booster only contained 10 grains versus the 256 grain booster of the M52 fuze series. The 10 grain booster ignited the M302's internal M19 burster charge (see photograph). A correct M82 fuze is actually difficult to come across anymore.
Best regards,
Randall

Hello
Bockscar, your pictures are very interestings. It wil be wonder if I know wich kind of M52 it is (is it a correct sentence ?).
As far I know, there are :
M52 : aluminium
M52 B1 : bakelite or plastic
M52 A1 : aluminium, but I don't know the dirrefence with M52
Perharps, one M52A1B1, bakelite. I guess, it's like the M52A1, but in bakelite.
In attachment, the M52 (alone) fuze.

Hello Bockscar,
Your fuze is technically an M525. These fuzes are a post Korean War design and are a modification of the M52 series. The modification consists of the substitution of the head assembly containing a delayed-arming mechanism in addition to the fireing pin mechanism (see photograph #2).

Fuze I/D
Thanks Guys, for letting me know just what type of fuze I have! - it was bought many years ago as a "Mortar Fuze" and that was that! There are no markings of any kind on the assembly that give any clues at all. I shall now accept the fact that it is a M525 with the delay modification in place...some of the interior workings can just be seen in place underneath the brass cover. I just took it that this was the way the fuze came from the factory but on looking at the illustrations posted earlier it is clear that this modification appeared later on.
Collection records now updated!

Hello
Thanks, Shelldude.
So, it is not very easy, isn't it ?
If I don't make any mistake :
M52A1 = M52B9 formerly M52B8 used with shells M43A1, M43A1B1.
M52A1B1 = M52B7 formerly M52B6 used with shells M49A2, M50A2, M43A1, M43A1B1, M56.
M52B7 is an alternative to M52A1B1.
M82 formerly M52B1E5, used with smoke shell M302.
M52B2 and M52B4 used with 81mm M57 et M57B1.
Thanks, Shelldude.

Holy cow! I've been looking everywhere for that diagram of the m525 arming delay mechanism! Does anyone have an electronic copy of that manual, or can someone who has a good copy of it get a good scan of the info on the m525 for me??
Thanks!
Ron
