He's got plenty of overpriced NOS sticky shed 7" Ampex 456 to test it with, so him saying he didn't have any tape is one statement proven to be false. Yes I agree... "Untested" often really means "Tested but didn't like the outcome" in eBay seller lingo.
Holy hell some moron even bought one of his tapes. 1/4" Ampex 456 on 7" inch reel from the sticky-shed era for $34.99 each plus shipping? WTF? Don't drink and browse eBay. LOL
