Bill,

The Lyman 48C as was used on the 1922 series Springfields came with what I call a deep base. It required inletting the wood to mount. Later Lyman 48S models have a base that is not so deep and it will fit on the receiver above the wood. A period correct 1903 Sporter or target rifle should have the earlier deep base model. A sporter just made up as a shooter would be fine with the later sight. The Lyman 48 for the Springfield has a step up in the windage/elevation slide. One just sold today on ebay for less than $120. The seller didn't know what rifle it would fit. The elevation scale will be numbered to 125. The ones referred to as the long slide was numbered to 150. Later Lyman 48S sights will have the elevation scale numbered to 60 or 90. Maybe some to a little higher number but not to 125. This is probably more than you wanted to know but here it is FWIW.
