3. Description of the gun (see the sketch)
(1) Barrel with three gradual strengthenings in the thickness. The length
is 5116 cm; right-hand rifling, 211 fields ahd Zia grooves; barrel ends
with a nuzzle brake, which supposedljy softens the recoil by 35 S.

eyes for road transportation. when the half-epades are opened they
have autematie catches which keep them in the open position. The
catches have to be pressed in when the gun is made rea4 for road
transportation. Improvement was suggested in the way of small wheels
fixed to the spade which could be raised and would thus aid in
shifting the gun oa small diztamcos (now the trails must be raised
in the air); new guns will allegedly have the small wheels.
