I have a number of Marble early 95 sights. The early versions from the 40s through the 1960s came in a Marbles
celophae/plastic bag with red and black description and sight No, Very well made. Garry Fellers used to have data on these sights-he is still in Ft, Worth but
his voice and health have declined.
I have one on my 1952 99EG, along with MANY on my Winchester Model 71-348s. All the 71s are pre-war models.
One M-71 is a 450 Alaskan with a Model 95 Marbles, backing up a Lyman 56 receiver sight.
If you use Lyman reciever -mounted sights, you need a Marbles 95 as a folding rear sight-
as a backup.
