Some annual Featherstone production number references:
March 16, 1894 Featherston said they were going to make 25,000 that season (1894). Have not found a later reference to confirm actual production number.
August 8, 1895 they said they made 45,000+ for 1895 season and were preparing to make 75,000 for 1896, but in December 10, 1896 they said they produced 60,000 in 1896.
