Richard Madsen Mygdal was an absolute gentleman. He was a frequent visitor to the TT paddock along with his wife, (who's Christian name I forget).
It was indeed Richard who rode in the 1953 Clubmans TT, and he was leading on the first lap, but fell off around Brandywell. 
He and his wife were very supportive of Dave's exploits around the Mountain Course.
Sadly missed along with his Grandson.
