My interest in my Tee Dee is rejuvenated with the recent topics. Is there any thing I can show you that would indicate when it was made? The front plastic part, nva, venturi, were missing when i got it and replaced. Also due to stupid actions on my part I have lost touch with the original cylinder. What cyl. should be on it?

The oldest cylinders from 1961 and later had thin wall with a small shoulder at the bottom. These were followed in the early 70-s by the stepped wall cylinders that had a deep and wide groove under the exhaust ports. The latest cylinders from the early 80- s and later are thick wall with straight contour..all these carry a No 4 stamped under the exhaust port, some thick wall cylinders had the number stamped in the exhaust port side.
