There is a seller on eBay with a couple of Murray bikes for sale. One is a track bike , the other is a white panel (1986) paint scheme; both are advertised with connections to the 7-Eleven team.

I wish the seller would post better pictures but there are a couple of things that interest me.
* shouldn't the team bikes have number tag mounts
* the color scheme (fade away direction) seems different than my 1986 frame below:
