There are not that many 3C reg russian a/c, in particular those what are permitted to go into US airspace.
E.g. IL76 and An12. There was also an IL18 at one time.
I was aware of an IL86 freighter but I understood this was on russian register "RA" tailnumber.
That Guppy reported bobbing around the US recently was also on the 3C register was it not, could this have been the cause for confusion?
