macgunner01,
About a year ago we watched some L (Lyman) marked Winchester frt sights sell for nearly $200 on both Ebay and GB.
Last one I seen sold since then was by the GB seller Hooah or something like that. His name is Carl. That L marked frt sight sold for about $180 if I recall correctly.
I remember him listing S'G' 15 rd mags starting at about $75.......

Here........I found him,

Just makes you want to count up your S'G' mags !!
