Don,

The background and photo file names appear to be taken from the Skin Diving History website.

Here is one of the first band guns powered by rubber loop bands most likely cut from tire inner tubes. This gun was patented in 1938 by Commander Yves Le Prieur and follows on from his cartridge and then gas powered "Nautilus" gun which was inspired by the fictional works of Jules Verne. Verne not only foresaw an electric powered true submarine with days of underwater endurance and a high submerged speed, he saw divers armed with underwater rifles for hunting after locking out of their submarine decades before any of this became a reality.

Commander Le Prieur has many diving inventions to his name and could be considered the father of underwater hunting with mechanical weapons, as well as his many diving related patents in the recreational and commercial area.

This is a later version of the gun with a modified spring gun handle and a longer travel barrel where the shock absorber spring has been replaced by a rubber version to slow the impeller unit that drives the spear from the gun.

and this is what the drive system would look like with the gun cocked to shoot.

The hooks would probably be further back in the side-slotted barrel than they are shown here, but this was most likely the first band gun to be a powerful weapon when prior to it was the 1937 spring gun of Alexandre Kramarenko and which in turn was the predecessor of many spring guns that were in their day the most powerful of underwater weapons (principally because band rubber was poor stuff and nothing like we have today).

The "declic" trigger mechanism used in the 1938 gun, basically a two-piece trigger with the sear lever also being a leaf spring as it bows downwards when the long trigger is pulled. Long triggers enable more fingers to wrap the trigger, most spring guns had big trigger finger guards to allow two fingers to pull on the trigger as often there is a tendency for this trigger mechanism type to initially move the spear very slightly rearwards against the pull being applied to the spear from the propulsion spring or bands.
