686 Onyx trap model with 32" barrels?
Yup. A 686 Onyx Pro. Think it may be a Cabela's exclusive as that is the only place I've found them listed.
Blued receiver, P. Beretta scroll with what looks like optima barrels, A sharp looking 680-something.
Hit the link above. If that doesn't work just go to Cabelas gun room and search for 686 Onyx.
Value used?. If that is indeed the gun, somewhere south of a comparable 682 Gold E since it is lacking adj. comb/adj. trigger.
Condition is everything.
