Caballoballo,
It is good to hear that the bongó now works fine for you!
Your words "old school sound" is mouthwatering  indeed 
  And yes, the eyes can be deceived quite easily the way you mention it.
I had a similar experience during my Gon Bops resto, the cow skin I mounted
on the tumba had some color deviations, so that the shell appeared to be out of round with
an uneven seating of the skin. Actually the tumba shell WAS a bit out of round BEFORE I 
epoxied the shell, but luckily enough I could fixed that and now all is well.
Congrats again to your Dandy set! Enjoy it as much as you can  

BTW my vintage LP bongó is bringing a fat smile onto my face everytime I play it,
such a good hembra punch and crisp macho
