Are you sure it's a Silverhawk? Some other Berettas had a silver hawk on the top lever. I bought a 20ga 426E (with a silver bird on the lever that is probably a hawk) last year for $1200, in 98%+ condition. PG/BT/SST, ejectors, 28", M&F. Uncut, original. Not a sweetheart deal, bought it over the counter in a retail gun shop.

Do you have pics?
