IQ4141 = Quinto 9 3/4", IC4141 = Conga 10 3/4", Tough Series (comfort curve rim, no metal bands outside, wood shell, outer fiberglass layer). No idea about the production year. My catalogue is from 1976.
I know, I almost shat myself, and grabbed these within an hour of them hitting craigslist. After reading some of the other posts around here, I am lead to believe that these came from '76 by the serial number.
