Help with a Musial bat - game used?
 

I'd appreciate some help. I bought this bat at an antique store in 1998 and had Stan sign it at a Tri Star signing that same year. I assumed the bat was a store model, but I recently saw a very similar bat being sold as game used. I know very little about identifying game used bats, so any help would be greatly appreciated. Thank you in advance.

No thoughts? I guess I'll just continue to assume that this is a store model.
