Us mech time fuze m67 a1

[havoc]

Hi once again,

Heres a interesting piece for you all. Picked it up in a Fuze Trade with four other various fuzes on the weekend.:angel:

I have found out some info on it so far,but must add im no expert on old US fuzes by any means. What i have found out so far is that it was used on the 8 inch HE projectile on the US Dreadnaught class of ship around 1903 ish.It was fitted in place of a normal PD Fuze before firing.It wasnt shipped in place. These guns were i believe used in US coastal batteries after their life ended on board these iron monsters.oh:

It is part strippable,the nose does come off as the pinch screws have been drilled out at some point.The time unit is still present and looks in good order.Unfortunatly the base screws are seized so cant take the unit out.But i think its best left for the time being.:tinysmile_eyebrow_t

I will post some more pictures of it later tonight.Unfortunatly it has a ding in the skirt edge and thread,outherwise its on good order with good threads.An interesting piece,not my thing really as i only collect WW2 German fuzes.But im sure it will bring in some great comments and interest on BOCN.

Best regards to all,

Clive. havoc.:tinysmile_fatgrin_t

Wel first of all it is'nt a naval fuze but a fuze for ground artillery for 4.5'', 105mm, 155mm, 8" and 240mm calibers. I am not sure wen it came into service but looking at the model number my best gues is somewhere in 1940 or 41.

Hi,
Yes i could be wrong here, as i said im really no expert on US Fuzes.
Heres what i found from a source in the US.

Ramming the projectile, 8-inch gun barbette carriage M1. Ammunition truck M17 for 8-inch gun barbette carriage M1.

SHELL, H.E., 8 INCH, M103 - STANDARD

The Shell, H.E., M103, is standard for 8 inch Guns, Mk. VI, Mod. 3A2, and M1. As fired the shell weighs 240 pounds and contains a bursting charge of 20.9 pounds of cast TNT which is detonated by a Fuze, P.D., M51A2, Mod. 3, or Fuze, Mechanical, Time, M67A1. The shell is shipped fuzed with a Fuze, P.D., M51A2, Mod. 3. When the Mechanical Time Fuze, M67A1 is used, it is necessary that the false ogive be removed and replaced after the shell has been refuzed with the mechanical time fuze.

For the 8 inch Gun, M1, two types of charges are provided for use with the Shell, H.E., M103. One is identified as a M9 (green bag) and the other as M10 (white bag). Both types are of the base and increment type.
The powder in the M9 charge is in the M1 class with an 87-10-3 formula. The grains have seven perforations and a web of .0695 inch. The complete charge weighs 76 pounds.
The powder in the M10 charge is alos in the M1 class with an 87-10-3 formula. The grains have seven perforations and a web of .1000 inch. The complete charge weighs 106 pounds.

Many thanks so far on your interest.

Best regards,
