Compact R-8 spindle on eBay

Someone was asking a while back about a compact R8 spindle.
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1779206580
is a current auction on eBay for such a spindle with three bearings.
There is no housing, nor do I see any provision for securing the
bearings. This has the look of someone that is making these for sale, it
sure doesn't look to me like it came out of any existing machine. Might
be worth looking and asking questions for anyone needing a short R8
spindle...
