Sorry about the earlier bare post... The stem tag holes are located only in the bow...if the holes you found are on both stems they are likely from something else. The stem tags are usually secured with 4 pins...not 2. The rail tags are usually mounted with 2. The typical tags are mounted across the stem. Some tags were mounted in line with the stem and if you subscribe to Kathryn's thoughts about this (no reason not to) then these would suggest dating between 1912 and 1916. With respect to such precise dating assumptions...these are estimates. Records for Morris do not exist.
