No I'm not going out with a Triumph bike, just trying to find manufacture date. I found an old Triumph bike at my co-op (not sure of the model) and I did a little research on Triumph. Started in 1884, made mostly English 3-speeds, then bought by Raleigh in 1954. I've been telling everyone that its at least 70 years old, assuming Raleigh didn't continue selling under the Triumpj name for any number of years afterwards. I've been interested in finding at least the correct year that the bike was made. I haven't been able to find any serial database for their bikes. I was hoping that someone here with more experience in the field of dating C&V bikes could help. Serial number is on the top tube-seat tube fillet. Here is a pic of the head badge and decal:
