Hi Greg. Your skillet appears to be possibly plated?
The Catalog number would indicate 1925 forward.
The Wood Handled Silverlite (plated) Wood Handled skillets are shown in a 1941 Wagner Catalog, so the dating would fall in the 1925-1941 (maybe a bit later).
Values would depend on condition of the piece. Plated pieces generally are less value unless the condition of the plating is near perfect!
Nice 'freebie' ! The best kind! :)
