Hi Frank, the Model 22 was made for Winchester by Laurona Arms (Eibar, Spain) in the mid 70's. The gun was in 12ga only, with 28" bbls (IC/Mod or M/F). It was a DT, PG, BTFE gun with an oil finished stock and light engraving on a black chrome (not blued) action.
This gun was in limited production and I have only seen one for sale along time ago. I also think it was offered with an english stock. I think the weight would be in the 7lbs range depending on wood density of course.
Hope this helped some.
All the best!!
Greg
