He has a Epi Casino up there that pretty clearly has a break repair, although it looks nicely done and has been over-sprayed and obfuscated to some extent. In that auction he states "there are repair mark on head" - so at least he seems aware of what to look for.
I understand the reservations, though. These Japan TBirds pop up enough to where I'd probably move on if there was any question at all. I used to have one too- great bass.
