I suspect you know that attaching a sling eyelet to the bottom of the barrels is a task that is more than drilling a hole in the bottom rib, tapping it to a screw thread pitch and screwing in a sling eyelet. Often the bottom rib alone cannot take the pressure of the weight of the rifle via a single threaded hole with a sling in use and rib will pull away from the barrels if you attach a sling eyelet that way. Heavy double rifles had/have a block between the barrels (placed there during barrel regulation) that the sling eyelet screwed into.

At the time of your Henry's build you often see an eyelet attachment of a few inches in length soldered to the bottom rib.

Does your double rifle have a under barrel attachment for a sling now? If it does not you will want to think about how much effect the addition of such a under barrel attachment will change the regulation of your barrels.
