Noticed this auction: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=4673&item=5752909331&rd=1&ssPageName=WDVW know little else about it save for what is described - ISTR someone asking about Oldham couplers here recently - it appears as if the seller is either making these, or having them made... dunno. Anyway, FYI.... Cheers John KB6SCO
