Jim:
It is not impossible, but it would require a lot of time, because one would have to go through all of the entries from the time Hunter started making 20 gauge guns until the new grades came out in late 1912. In most instances, the 20 gauges are mixed in with all of the others.
At the present time, the LCSCA doesn't have time to do this type of research. I suggest that you contact David Kennedy at the Cody Firearms Museum. His staff may do the work on a contract basis.
