Wrong thread for all of this really, but I am bidding on the tape version. The Super8 is the cineovision transfer which is only of interest for the mono soundtrack really.

The tape is most likely CV and probably recorded from a TV broadcast, but still could be interesting. It might be EAIJ Type 1, which could indicate a dupe from something else which would also be interesting. I have a CV deck, but not an EAIJ one, either way I'll pick it up if it doesn't go for much.

It is 1/2 inch, so as Puggo said, most lilkely one of the two.
