I did some more Googling and discovered the collector is Central Machinery, from Harbor Freight, about $200.

The Wynn filter is separate, has good reviews and cost about $177.

I may offer $250 and see what happens.

LumberJocks forum mentions some seal (of the Wynn filter?) not fitting securely on canister of a Delta Collector. I need to go reread that posting, those postings.
