The following year Heckles was again entered by Beart in both the Senior and Junior Manx Grand Prix events. After both bikes went well in practice, the 500, after breaking the lap record twice, retired on the 4th lap. In the Junior event, Heckles, on this bike, was leading the race on the 2nd lap. After a stop for fuel at the end of the 2nd lap, Heckles dropped down the order but retook the lead on the 5th lap, only to stop on the final lap after running out of fuel. He scrounged some petrol from another competitor and managed to finish the race, albeit in 42nd place.
Following the race, Beart sold both machines (350 and 500) for the princely sum of £1,000 to Hector Dugdale, the well-known Cheshire dealer/entrant, who in turn sold on the 350 to a Liverpudlian named Alan Prange. Prange raced it at only a few local meetings before passing the bike on to Heckles' sponsor at the time, Bob Vincent from Wigan, enabling Heckles to race the machine again. He entered a few races at Aintree and Oulton Park, and competed in the 1969 Junior TT, finishing 11th at an average speed of 90mph.
When Bob Vincent died, Keith Heckles bought the bike from his widow around 1972. He did not race the Manx very often after that, but did loan it to his good friend Frank Steele to race in the Manx Grand Prix in 1976, possibly its final race. Keith subsequently sold the 350 to the well-known North-of-England Norton collector Eric Biddle. A few years later, Biddle sold the Norton to Mike Steele of Leeds. Mike Steele carried out some restoration work, calling on Keith Heckles to overhaul the motor for him (see 1994 Classic Motorcycling Legends article on file) and paraded the bike occasionally.
During 1996 Steele was approached by Patrick Godet, who was restoring the 1967 Beart 500 Manx for Jean-Christophe Ollieric, a Parisian enthusiast. Godet needed an original Jakeman fairing to copy for the 500, and asked Mike Steele if he could borrow the 350's fairing in order to make a pattern. During the course of discussions it transpired that Steele was prepared to part with the bike, and it was duly purchased by Ollieric in 1996."
