Sash tilt lock

I cannot find any identifying marks, numbers, or names on these two parts. The only reason I think they are Gapco windows is I talked to an old timer that framed and finished most of the houses in that neighborhood and that's what he told me. I have two windows that will not lock in the track. The palstic "L" shaped piece has "raise sash 2" before tilting. The rectangular metal piece has the square end broken off that fits into the white plastic piece that slides in the track.
