We find very similar unknown mortar round, in Poland.
But with holes on top, we think they are smoke...
British Stokes design?

Stokes Pistol etc

The top one is a regular Stokes Pistol, formal 1915 designation is 'Pistol, HE Bomb, 3-inch Stokes Trench Howitzer Mark I' (or II or III). The lower one looks like the No 146 Allways Fuze without the safety band.
what was an allways fuze or any detail etc, i also saw the same type outside Monchy le preux last year, so any info would be appreciated
Stokes Pistol etc

An 'allways' fuze is designed to function on impact irrespective of the attitude of the projectile on striking (the mortar bombs of the type shown typically tumbled in flight). The 146 fuze is described below in a piece of work that Ian Hogg did for the military. Although the fuze design is attributed to Vandevell it was his business partner Albert Midgley that really designed the fuze.

"Fuze, Percussion, Spigot, No 146
Design IDW B/65. CA.Vandervell design of allways fuze, similar in concept to the Fuze No 145 but using a ball. The mechanism consisted of a needle pellet and a detonator pellet, kept apart by creep springs. The needle pellet had a coned upper surface, and between this and the coned interior of the fuze nose was a steel ball. The two pellets were separated by a safety bar attached to a weighted tape. On firing the tape flew free and withdraw the safety bar. On landing, whichever was the uppermost of the two pellets would ride down and bring needle and detonator into contact. If the fuze landed on its side the ball moved across the coned surfaces and forced the needle pellet down on to the detonator. Broadly speaking this has been the operating principle of most allways fuzes ever since. For use with the 3in Stokes trench mortar

I have just joined this forum. I am interested in WW1 Mortars, particularly the Stokes. I am also interested in the early Brandt mortars including the pneumatic mortar.
