Unmarked Front Sight|Winchester Sights|Forum|Winchester Collector

With some pictures and description, was hoping I might find what this front sight is. It is not marked but is somewhat similar to a Lyman #17 but no provision to change posts or reticule.

The base is ¾ inch wide, the slot is a little smaller than the customary 3/8” width measuring 0.337 inches. The tube is ¾ inch long and is 0.462” outside diameter. Overall height is 0.578 inches high from bottom of base to the top of the tube.

Any thoughts? Any idea what it might be worth.

Thanks for any input and help.
