W.W Greener wrote in Modern breechloaders: sporting and military in 1871 (page 214):
- This rifle is called No.2, to distinguish it from the first Comblain, which is a modification of the Snider principle. The Comblain no 2 has the vertical sliding block and guard lever of the Sharp rifle; but the arrangement for exploding the cartridge is different.
- The mechanism of the lock is fixed in the breech block, which consists of the ordinary main-spring acting upon a tumbler by a swivel. The tumbler and striker are made in one piece; the scear and trigger are also in one piece . By depressing the lever the breech block is brought down, the cartridge-case extracted and the rifle is cocked. A fresh cartridge being inserted, and the lever returned, the rifle is ready for firing.
- The hinge screw can be removed without the aid of a turnscrew, which arrangement allows the breech block and lock to be taken out for the purpose of cleaning.
- The breech arrangement is strong and simple. It is used by the Belgian volunteers, and has been severely tested both at Liege and Wimbledon.
