Fender Stratocaster knob set four spoke 1980s USA also Fender Japan? Free US Ship

This a set of Fender Stratocasters from the 1980s, I think they actually start showing up around 1979 and into at least the early 1990s. They have four spokes and the appropriate molding marks on the bottom, also a small indentation on the underside edge below the 6 where they were pulled from a "tree".  I've also seen identical knobs being sold as coming from mid-80s Japanese Fenders so I leave it to the Fender experts to nail down the exact years these were used. They look pretty good, the white has gotten a little darker from age and they are a bit dirty on the sides. Some scratches on the bottoms from when removed but no cracks.  Shipping will be FREE in the US, $20 elsewhere (assuming USPS First Class international service is available to your country).  I may be posting some other knobs soon from many decades of accumulating parts, but I no longer have any 50s parts or Pre-CBS as far as I can tell.
