Mounting screws for Winchester Model 61 tang sight.|Winchester .22 Rim Fire|Forum|Winchester Collector

I am looking for Lyman W61 tang sight  mounting screws (Winchester Mdl 61).  I aquired a new in the box W61 ( old stock) tang sight. The mounting screws were used on another rifle by previous owner. I bought several newly made sets on ebay but the screw body is too big. A newly made 61 forearm screw will thread in fine but is a little loose. An old original Win Mdl. 1890 forearm screw fits perfect. Would like to buy new original (old stock) mounting screws ( I know I might be dreaming but you never know) or newly made screws that will fit right.

Not sure is this post should go under 22 rifles or sights but put it here. Dick
