I'm not quite sure, but it seems to me, that I found an old pro car from Mr. Williams in ebay. I just wanted to have such an old chassis type, but after receiving it, many things came up very strange....
I will post these pics, armature with three colors and strange balanced arm, body stiffeners, front wheels split on surface, flatened axles, and other things looking not mainstream.Typical for that time....
Look at the pics, Williams is engraved in front of the droparm and I found the name Williams in the article of the big Nutley race, where Gorski won. Have a look at car model July 1969, page 14. May be the dokktor can help.
