Greetings Stephen: Congratulations on this rare acquisition. I would be very interested in finding out the serial number of the O reproducer and if it is the iron body brass topped variety. I am curious if Edison really changed over to the potmetal body O on the Triumphs. With your machine having such provenance the O is most likely original. Only about 500 Triumphs were made after yours so it is a really good buy and rare in its own way. Again, congratulations on getting it!
