Redfield 102-S (Springfield) I think it is.,, they go back to at least the mid 30's.
A non micro adj sight.
Loosen the elevation knob and slide the bar up and down,,then relock the slide in position.
Windage peep has 2 opposing screws holding it in position. Loosen and slide the bar L&R as needed,,then relock in position with the screws.
Their micro adj sight was the #90 and #100.
The difference betw these 2 was the #100 you could QD the elevation slide by depressing a slide lock button.
On the #90 there was no QD release for the elevation slide. You had to back the Elevation adj screw all the way out with the slide to remove it.
As far as the rifle,,The right side of the stock looks like it was shaved down a bit from it's orig configuration and the ejection port cut-out enlarged a little. The wood looks somewhat rougher in that area of the stock than the rest. Maybe it was damaged at some point, even scared from charing/being too close to a fire or heat source. Then the surface damage filed or otherwise removed down to solid wood.
What ever,,it seems like an awfully nice Springfield sporter and the family connection makes it all that much more a treasure.
