a couple of fuzes (for the 25pdr I think?) T&P

[butterfly]

I picked up a couple of fuzes today, not really knowing what they were but appeared to be in good order. A little search on bocn and I 'think' I have been able to identify them as 25pdr fuzes ?
I really have little idea about these so any help would be welcome.

I was told they originally belonged to a man who worked as a machinist at the factory where these were produced.

One I can see has clear markings as a No221 fuze, the other, well the markings have been 'removed' so need a little help with this one.

Not really my field, but couldnt resist these - Kev

The second fuze looks like a 222B

They are both Time and Percussion Fuzes

The 221 was used on 25lb smoke BE shells amongst others.

J.A.P. - J.A. Prestwich, Tottenham, N17. At one point probably made almost all the two stroke engines used by British motorcycles.

UK did not produce fuzes specifically for 25-pr. It's just that 25p-pr had the largest choice of shells, I'd suggest that No 222 was used by 4.5 G, 5.5 and 7.2 as well as 25-pr, No 221 would be limited to 25-pr and 5.5, not sure about 3.7 How.

According to http://nigelef.tripod.com/ammo.htm#FUZES

No 210 - a mechanical time (MT) fuze for use with HE shells that was introduced early in the war and does not appear to have been widely used, it was deemed obsolescent by late 1943. Its lack of a percussion function made it less than ideal. 60 second maximum time. No 213 - a MT and percussion fuze for use with HE introduced in 1944.
No 183 - time only by combustion used with star shells. 30 second maximum time.
No 188 - time only by combustion used with star shells. 48 second maximum time.
No 220 - time and percussion fuze used early in the war with non-streamlined smoke shells. The time function was by combustion.
No 221 - a time and percussion (graze action) fuze used with streamlined base ejection smoke, star, flare and chemical shells. The time function was by combustion. 50 second maximum time.
No 222 - a time and percussion (graze action) fuze used with HE shells including airburst ranging. Could also be used with BE smoke set to 0 for local emergency use. The time function was by combustion, basically it was a No 221 fuze with a gaine added to enable it to detonate exploders. 50 second maximum time.

Airburst ranging was not the same as an HE shoot with MT fuze. Airburst ranging was used against targets in depth using high airburst with cross observation usually from the corps survey regt RA, hostile batteries were one important type of target that could be engaged this way.

Very nice finds, especially in unfilled factory new condition.

The 221 was also used with the 3 inch smoke mortar bomb. Nice fuzes you have, now jealous I am (stop it Yoda).
