Swedish Fuzes.

[ron3350]

I would like information on the model, makers and calibres of projectiles that use these fuzes.
Both seem the same except for the steel nose or all brass construction. I guess both are Swedish?

The brass fuze has the Bofors maker arrow B on the base. The steel one is plain and has P.W. as a maker.
The thread is 50mm diameter and 8 TPI. Not metric.
Lengths are 88mm brass, 89mm steel. 73mm top brass, 73.5mm steel.

The steel top on the brass fuze comes off when I push in a spring-loaded pin. What purpose would this serve?
Any information is appreciated. Ron.

Ron3350,

The Dutch called it No 6 and it was used in the Dutch indies.

Hello,
Same delay selector on steel fuze ?

 

[ron3350]

Yes exactly the same except for the steel nose and different marking.
I should have shown the selector photo view.

Very nice and also rare fuzes!
These fuzes were used by the following guns of the Dutch colonial army:
-mountain gun 7,5 cm L/20 (7,5 berg)- case 75 x 212 R
-field gun 7,5 cm L/30 (7,5 veld) - case 75 x 278 R
-howitser 10,5 cm L/22 (10,5 hw) - case 105 x 250 R.

Fuzes made by Bofors were all brass, fuzes made locally by the Dutch may have brass or steel noses. P.W. = Pyrotechnische Werkplaats Bandung

The steel top, when removed, made the fuze more sensitive on impact. So when firing thru bush the steel top had to remain in place.

Here is the comparison between both No6 M25 fuzes. Some of these fuzes appeared in Australia about 12 years ago.
The selector screws are not exactly the same. Thanks everyone for the great information.

Does anyone have external images of the two rounds this fuze is used on? Greif provided great cutaways.
