This Lyman manufactured No. 1 folding tang peep sight with small turn down peep is marked on the underside of the base with a "WS" indicating that this sight is for the Winchester model 1890 & 1906 takedown slide action rimfire rifles. The overall condition is very good exhibiting a brownish gray patina with some of its original blue finish in protected areas and a few freckles of rust staining. The mounting screws are not included. (file photo)
