This is a vintage Daisy telescope sight made to fit a Red Ryder, or Model 25 BB gun. It is marked Plymouth Michigan. This one is in unusually good condition, and retains between 80 to 85% of the original finish. It still has the rubber eye piece, mounting brackets, and front plastic lens. We’re not entirely sure when these where manufactured other than being sometime in the mid to late 30’s and early 40’s.
These are pretty rare, especially with all of their parts, and would make a great addition to your vintage Daisy airgun.
