schon r1 year?

Odds are it is post 93. You need to take measurements of the pin. If I recall, pre93 pins have a smaller ID than post 93.
 
Then it is technically a Runde era as he was there until 92.
82-85 had stitch rings standard, nickel rings extra
85-92 nickel rings standard, stitch rings extra.

odds are it is an 85-92.
