THE NEW AUSTRIAN FIELD GUNS. 
mical reasons, it may have been most judicious for Austria to adopt this 
material. 1 
Fig. 1 . 
Fig. 2. 
(A,) The 9 C Gun* is shown in Pigs. 1 and 2. The axis of the trunnions is 
in the same horizontal plane as that of the piece, and the trunnion arms them¬ 
selves are hollowed out conically on the face. The piece is vented vertically 
through the metal of the piece a little in front of breech-block slot. The 
latter is cut laterally near the breech end right through the piece. The gun 
is sighted at the right side with a small screw sight, screwed into a patch on 
the gun in front of the trunnions, and a tangent sight, secured in an inclined 
socket, Jc, at breech end of the piece. The clamping screw for this socket 
is shown at l (Pig. 1). 
Upon the upper surface of the gun, a little in advance of the vent, is a 
flat surface (y, Pig. 1), for the reception of a quadrant, if necessary. 
At the breech end the gun. terminate^ in a plane surface at right angles to 
the axis of the piece, with the corners rounded off. 
Looking at Pig. 2, we see that the bore, shot, and powder-chambers have 
different calibres, as given in Table I., and that only the bore proper (S^ 0 
in calibre) is rifled; the rifling being square, and many-groove, with a twist 
of 1 in 45.

* This description will also answer for the 8 C (7‘5 C ) gun which only differs from the 9 C (8'7 C ') in 
dimensions as shown in Table I.
