I have some that fits the description, Ted. I'll begin with this one, much like yours. This is an Ithaca SKB 200E. It's a 20 ga. with 28" tubes, weighs 6 lbs. 6 oz., and the dutiful Ithaca Raybar front sight. I won it at auction about 10 years ago. It appeared to be in unfired condition when it arrived. White line spacers, too!!
I'm going on memory, but I'm thinking it's choked IC right and MOD left. Wish it had double triggers like yours, but it is what it is. Works perfectly, and was carried on my first trip for Gambel's quail in AZ. Went two for three with it that morning. She'll digest anything I feed her. The wood in the butt is strange, not really attractive in the usual sense, but has a translucent look, with very subtle figuring.
