76mm Fuze Info Needed

[Darren]

Pictured below is the fuze that i am looking for info on, i believe it is a PD fuze for the 76mm Oto Melara Navel Shell? Please correct me if im wrong.

Stampings are: OP 76 mod.1 2-FBO-80

I am looking for diagrams of the internals, mainly the clockwork delay mechanism (in the last photo), also any other general info about this fuze.

Could you specify a country please.

Not sure to be honest, I will have to post a picture of the fuze that I have for a positive ID. Will post tomorrow when I'm back on my main computer. I believe that the fuze I have is for the 76mm Oto Melara Navel Round but wanted info just to make sure.

Thank you EOD for the information, that is great. Any idea what any of the other markings translate to? Date maybe?

Hello


In the worldfuze fuze identification, page 166, there is the OP76 Mod 1.

But nothing about the mechanism.

Thanks for the info Pascal, that is a little more info about it that I didn't know so that's great. I've searched the Internet high and low but there doesn't seem to be any info out there at all about these fuzes.

Great info book on all fuzes in general, will be keeping that one for reference. Doesnt give much detail at all about this 76mm fuze though and have been unable to find out any other info at all. There seems to be no mention of this type of fuze on the internet as ive searched high and low. Bit of a mystery!

There were a number of countries that used the 76.2mm Oto Malera gun. In use with the U.S. Navy, it was a fully automatic machine. Since the barrel would be blocked to prevent seawater from entering during the normal tour of duty, the first few rounds to be fired were inert loaded with dummy fuzes to clear the muzzle seal. The rounds to follow were either PD or proximity fuzed.

Our Navy uses the same gun (Dutch navy), just happen to be a part of that navy, could ask the weapon-engineers if they know anything? I ain't promissing anything, might still be "NATO Confidential" so then i can't post it here.....

Darren,

Everything that you have received on the fuze so far is correct as to manufacturer, etc. It is the OP 76 Mod 1 version of the point detonating fuze used on the 76/62mm Oto Melara naval gun system. I am the one who wrote/published the Worldwide Fuze ID Guide, but do not have all of the original support documents anymore. I have attached an illustration from a Borletti manual that shows the interior and the escapement mechanism. Hopefully it will answer some of your questions.

Thanks EODGUY, that's a great help and thank you for the diagram.
