What we have here is a 1961 T110 ( Non Matching Numbers ) with the one year only Duplex Frame.
A rather natty Cafe Racer, but seeing as most people who want these are over 45 years old and can't bear the thought of riding a bike with Clip On's and Rear Sets!!! ( I personally LOVE IT ) it's going to become a Desert Sled, Just like the Original Buck Smith Sled that has emerged recently.
This is also a Duplex Framed 61, so I reckon with a bit of neat spanner work in my Workshop, what will emerge will be a lovely thing to behold, and a hoot to ride.
I would imagine the final price will be between £7-8500 depending on final spec and weather you want fresh paint and shiny bits or good, old, patina.  So. if you fanct one, get intouch and slap a deposit down, you will be updated with its progress throughout its build and will, without question, be over the moon with the final result. 
As was the last, lucky customer who took delivery of his 71 TR6 Sled.
