To my understanding, that is correct. Strada/Pista.
I've been led to believe the C is for c-record, but I'm not positive -- if you have the matching cup + cages for the spindle, and it has 11 bearings, its Chorus/Croce. 14, C-Record. (1/4" v. 7/32" bearings)
The 111mm is correct for C-Record, Croce + Chorus of the era. Even the 1984 C-Record. English or Italian.
