Here's the 110 page from the 1968 catalog along with all the spec's for the different models.



If the stock is original it's either a 110ML or 110MCL. Given the stock is for a blind magazine I'd be inclined to say it's a 110ML, but looking at the photo's of the magazine box shows what appears to be a detachable magazine surround and box with all the release hardware in place. This schematic from Numrick's isn't much help either as it shows all three magazine variations in one schematic but doesn't specify what parts were unique to what model.
