Kona Cindercone or is it?

Columbus and Tange are manufacturers.
A cheap columbus tube sounds duller than a nice Tange one.
I doubt you can tell manufacturer by "ring" - excepting perhaps TrueTemper
But you can certainly tell quality.

Tube length, joins and braze-ons all have an effect too.

Perhaps they filled the stay mounts because the threads were stripped.

Just from my experience mainly with Tange Prestige but you can definitely tell the difference between Prestige whether that's a 88 Pine Mountain to a 93 Explosif. it's got a certain unique sound compared to say a 88 Muirwoods or a 93 Lavadome with bog standard tubesets which just sound dull really. This part is just my opinion but where you really notice it is when it's just a frame with nothing at all attached.

The rack mounts could be that reason when they went to spray it just cut them off.
