Leupold made a reproduction of the Lyman Alaskan (called the Leupold Alaskan for some strange reason) which was a 7/8" tube scope. I think the Lyman was only 2.5 power but the "reproductions" were 2.5, 4x and 6x. I have the 4x. It is a very nice if plain scope, looks very old fashioned but the glass is probably better than the old Lymans. It is a steel tube and pretty heavy. I will never sell it, but if lucky you might find one used. I also found some rings that fit the scope, not common but they exist. I might take a pic if you care.
