The shells on them are the original “Highliners”. They actually made it in to production about 12 years ago under that name in a bright yellow box (I’ve got a pile of them sitting here). But before then they had been advertising for about 5 years with nothing to show for it. When they finally came out they were like $45 each and this was back when that was outrageous for something plastic. An Atlas RS-3 with a Kato drive was only $40 bucks. So they sat on the shelf.
