Wanted: Winchester 69A magazines for 22 rimfire shorts

I am looking for the rare 22 rimfire magazine that was designed specifically to feed the 22 short shells into the Winchester 69A.

I would also be interested in any original Winchester 69A magazines that are identifiable by the complete Winchester name stamped on the bottom of the mag verses the after market ones that only have a W stamped on the bottom.

Thanks for any info

Bill
