Container Smoke No.1 Mk I & No. 2 Mk I (attached to the Shell Practice 25 and 60 lb.

Only the first nine are WW-2 productions and the other eight are post-war.
From the phosphorous warhead is little information available. As far as I know these were “field made” by attaching the “Shell Smoke 25 lb. Mk I” from the 5 inch Barrage Rocket “Sea Mattress” to the 3 inch rocket motor. Some UXO’s of these have been found in the Netherlands. These were also named “specials”.
There is not much information about the 12 lb. GP warhead.
The container smoke is also post war.

There also seems to be a Chemical Warhead, maybe some one has more info.
