Doubt if that information will ever be available based on the information that remains in the pre-13 shipping records, as frame size was typically not noted prior to about 1918-19. The FW frame was introduced in 1907, and I've seen a fair number of FW framed 12 and 16 gauge guns shipped prior to 1913; and lots more shipped after 1913, but prior to 1918, that were constructed on the FW frame. It was only after the 1918 bankruptcy and reorganization that shipping record details were changed to include frame size and options.
