Silvers,
Could the stamping on your forearm iron have been "PATENTS PENDING"? See The Double Gun Journal, Volume Twelve, Issue 1, page 96 for the two forearms for serial number 35. One is stamped PATENTS PENDING and the other is engraved. That gun has the A.H. Fox & G.A. Horne ejectors, but was made well before the patent was actually granted. Probably before it was even applied for on July 24, 1907. AHFGCo. mentioned ejectors even in their early, 1906-vintage, Finest Gun in the World catalogues, but their magazine advertising didn't push ejectors until the 1911 F.T. Russell style.
