Want to buy: Graduated Peep Sight leaf for thick base|Winchester Swap Meet|Forum|Winchester Collector

I recently acquired a thick base for a Graduated Peep Sight.  It needs a leaf to complete it.  I think the leaf for the early model thick base graduated peep is different than the later thin base variations.  Photos below with what I have and what I need.  I have an extra eye cup and backing plate so that is not critical.  Please let me know if you have one in your spares box.
