Modified 25-pounder guns

[Godwin Hampton]

According to the 1957 user handbook for the 25 pounder, the original carriage was (logically!) the Mark 1. This was modified into the narrower Mk 2, as well explained above. The Mk 3 was the Mk 2 with the joint to allow higher elevation, and no other modification. Therefore the shields (with flaps) for the Mk 2 and Mk 3 were identical.
