L-Frame grip question

[lionhunter]

I have two pair of S&W 1985 dated target grips that were taken off new Mdl 686 L-Frames in the mid-1980s. Never used, still have the inspection sticker on the bottom. What frame size will these fit: K, L, N? Value? Thanks

I understand they fit K and L frames, not N. No idea on the value.
