Heyoh -
So, I have an early '60, low #'d supra that is in super condition, except the top rim is slightly crimped from being dropped (still in round & sound). It's COB. Just picked up an early, low #'d acrolite and low-and-behold the top hoop's a COB. I am itching to switch them but they are not EXACTLY the same - but I have no reason to believe either is non-Ludwig.
Would Ludwig have used different COB style hoops on supra's & acro's?
Thanks - Chris
