    Apologies for resurrecting an old thread - would I be correct in thinking that when you see "80" and "10.R" (or even "R10") on FIAT / LOBO marked heads (such in TTR's head collection picture) that they correspond to the respective ISO 8.8 and 10.9 classes ? Does the "R" represent the coating/finish type?

    I don't have definitive answers to either, but your first assumption, i.e. "thinking", seems logical.
    The "R" might also refer to some other (than "coating/finish") technical spec.
