ONEIDA COMMUNITY ,N.Y.

Was hoping one of the real OC experts would answer here but no luck so I will give it a shot. The double cast jaw traps like the #1 size pictured here were made by the Oneida Community between 1909 and early 1924 in both single longspring and single underspring(jump) traps and in sizes #1 and #1 1/2. All are marked either 91 or 91 1/2 and are collectible. The #1 1/2 sizes are more difficult to find than the #1 size. The trap pictured appears to be in good collectible condition and would likely sell for between 10 and 20 dollars retail as would a comparable long spring version. The #1 1/2 size traps might bring double that amount, especially if they were in very nice condition. As with many collectible traps, unusual and rare variations exist. The single underspring trap pictured above was made for a very brief period(likely at the start of production) with a solid pan(no stamped out V) and those traps are scarce, especially if nice, and will bring 100.00 or more on the retail market.

Thank you for taking the time to post the information above. It is greatly appreciated...Have a Great day.
