I am reasonably confident that it isn't a 1905 Kennebec. The company was founded around 1909 and their oldest serial numbers start with 1001 in January of 1910. The Kennebec with serial number 8084 is from 1912, the Carleton with this number is from 1911 and the Old Town is from 1907. Let me know what you find. Thanks,
