MkI backsights

Are many members seeing Long Branch and Savage marked MkI backsights? They certainly are hard to find in my AO. I did locate a like new LB last summer and finally after several years a Savage this week. It was on a 44 Savage sporter that well be return to resemble original, with a Mk 2 flip sight. Now to find a S marked Mk 2.
