I would like to hear positive and negative points on the Browning Superposed from actual users.

I am considering purchasing one in 12ga. I'd like 28" bbls choked mod/full. I currently shoot SxS's but thought I'd give the O/U a try. I am looking at a couple. One mfg in the late 50's and the other mfg in the mid 60's. I know about salt wood and I know the chokes are fixed. Any reason why one of these would not be a good pheasant gun? Thank you,
