Help Identifying A Vintage Tank

It looks very much like my ‘ 68 Daytona’s tank . Is it missing a bracket at the back with a 3/4” hole ?
It could be a Bonneville , but mine is 45 miles away . B’ Ville would be 1 1/2” longer . One the two with dual petcocks.

 

There is a coating company in the Chicago named Archer Coatings , I think that can redo both the inside and outside of tank in “ terne coating “ like a car has . Cost $80 . Catch is it must be paint free to avoid contaminating their tanks . Wish I had done this - - .
