Was out of town on business for a few days. Good to be back.
It's a NUT 1922 998cc V-Twin
"Around the beginning of 1912 Sir William Angus, Sanderson & Co Ltd began producing, from their St Thomas St., Newcastle premises, the first motorcycles designated NUT (which stood for Newcastle Upon Tyne) employing the twin expertise of, I believe, Jack Hall, and certainly that of Hugh Mason. Mason acted as manager, designer, test rider and racer. Although Mason had ridden before in the IOM TT (in 1911 [Senior retired] and 1912 [Senior 7th] both for Matchless), and had a formidable reputation in trials and speed events, it was 1913 which was to be his and NUT’s annus mirabilis.
In that year, Mason and his works NUT machines, amongst other achievements, captured the Brooklands Junior TT, The Isle Of Man Junior TT, The Scottish Lightweight Championship, The Brooklands Six Hour Race, and the Brooklands Solo Ten Mile Scratch Race, as well as establishing ten long distance records in the 350cc class."
