No, think it was just a heads-up for a Revox A700 motor at what looks like a reasonable price for once ($29.95) on eBay. Looks like some typos snuck into in the subject, though.
Quite appropriate to list here (pretty sure the OP is not the seller), and I would have thought it would be sold already - what Studer/Revox part EVER sells for under $30? - but no, it is still available.
No affiliation of course.
