I noticed that the same seller who had the rubidium cell also had an HP 58533A for sale: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=290047717429
Don't know anything about those, but it looks a LOT like a Trimble Thunderbolt. If it's built by HP to the same standards and specifications as the Thunderbolt, and if it works at all, it ought to be a nice unit.
