I have two Thule 559 MTB PRO car roof bike carriers. I have seen them classed as "antiques" in a Google search. I have not used them for about 30 years and I found them on a high deep shelf at the back of the garden shed. Unfortunately, mice have eaten most of the boxes, and the keys are missing. They will still function, but can't be locked. Preferably, they need a "Good Home" rather than the tip. Keys (N030 & N031) can be bought on-line for about £5 each.
The links below give some information on them
