6G3 Deluxe cab quirks

[Mars-Hall]

Just received my 63 Deluxe today.  Just want to check with experts on the provenance of this cab.  First, it was promoted as all original and mint.  The amp is clean but the handle looks and feels like a repro.  Is there a way to determine from this photo or otherwise?  Also, this is the first time I've seen a tube chart glued to the bottom right hand side of the cab.  Usually find them mid way up on the inside of the left side.

I've never seen that. Looks like a red flag to me.
