betterment of firearms design. A number of these improvements met with little favor despite their virtues, and a few led to litigation ancl considerable controversy. Perhaps the most widely acccptcd of Manton's designs was the elevated rib for sighting double-barrel arms, and second was his patent brccch complete with drain hole, which made it possible for double-barrel guns to be constructed in a more streamlined form. Less popular were his V-shapcd priming pan and his gravitational safety stop designed to prevent the accidental discharge of a gun while a chargc was being rammed home.
Most controversial of all were Manton's contributions to the development of the percussion ignition system. In 1816 he patented a percussion pellet lock which Forsyth claimed was an infringement on his patent, and in the suit which followed Forsvth won. Thereafter Man-
m ton turned to the tube lock and obtained a patent on it in 1818. Again Forsyth sued, but his patent was about to expire, ancl although the court found in his favor. Mantón was soon able to put his lock into production. Finally, Manton's friends also advanced him as having developed the true percussion cap. If he did so, he failed to patent it, and the claim is generally disregarded today.— Harold L. Peterson.

Ithaca Model 37 Featherlight Shotgun
Ithaca M66 Parts
The Ithaca Gun Co. of Ithaca, N. Y., started manufacturing guns in a small wood building on the banks of Fall Creek in 1880. Their first model was a 12-ga. hammer gun, and from this they evolved a series of single- and double-barrel shotguns. Although they have manufactured M1911A1 automatic pistols, M6 survival weapons, and M3A1 sub-machine guns under World War II government contracts, and are currently producing a cal. .22rifle, their reputation has been built on their trap guns, their double-barrel guns, and the Model 37 Featherlight slide-action shotgun.
The Featherlight was first offered in 1937. It won immediate acclaim since it was a good pound lighter than its nearest competitor. This weight reduction was accomplished by clever design rather than by the use of light alloys. The number of operating parts was kept to a minimum and they were lightened where possible.
As with most slide-action shotguns, the bolt has no locking lugs or separate locking block. The slide tips the end of the bolt up as it is pulled forward. When the end of the bolt is locked into the top of the receiver, the slide supports it from below to prevent unlocking.
Another good design feature is the bottom ejection system which prevents rain from getting into the gun when
1 Before attempting to remove barrel, unload magazine and chamber. To empty magazine, push in spring shell stop (13) on inside of receiver as shown. Ease rounds out one by one. Pull back on slide release on forward side of trigger guard and pull back slide handle to empty chamber handled normally. This system also provides a good safety factor since it protects the face from brass particles or powder burns resulting from defective-shell bursts. Since ejection is downward, the Featherlight is a great favorite with left-handed shooters. Ithaca makes a left-hand safety that can be easily in-
