I may be wrong, but to my knowledge, they didn't make a combo. Someone has fitted a single bbl to your Superior grade receiver. IMHO.First I haven't been able to find a model number or grade just serial numbers. This one has a barrel selector should it have an O/U barrel with it? Other wise what are your opinions?
Not an accurate statement.After 1976, production moved to Italy, but the Superior only came in an O/U, discontinued in 1988 and SXS discontinued in 1985.
