EELCO MFG AND SUPPLY COMPANY... Vintage eelco knob from 1960's, I believe it is a stingray for Corvette..  It has some imperfections and scratches, etc.. in chrome, probably could be rechromed and look very good or use as is.. Takes a set screw and a insert, so, it can fit many  shifters..  Looks like it has a date of 63, but not positive..   Pictures of Stingrays are only for comparison and not included.. Good luck finding another one of these!! Sold as is, as shown, Free shipping to Continental U.S., Elsewhere may be charge..          Originally, the background on EElco knobs were all painted black, as for this knob, most or almost every bit is worn off..         Added a Hotrod magazine ad that shows some of the knobs available, but still haven't found an ad with this design..
