While in the Isle of man for the Classic TT races, I was presented with a package and told I could have it for one night only.
The package contained what is very probably the last Dyno Room record book of Norton Motors.
The entries were all in pencil, and time has rendered many difficult to read, but not having any means to scan the pages, I took a photo of them, using the only camera I had, a small cheap item made in the Far East.
Because of the dates of the entries, I hoped it might contain details of Domiracer tests, but unfortunately not. The was however, record of tests conducted with a 650 twin engine, and I am including this by way of affording a glimpse into what was a world known to but a very few who were privelidged to work in the test shop.
The book was a record of tests conducted on the Manx engine in it's various forms, and included a special 250 unit the factory built for Frank Cope, as well as engines for Esso and others, including 350 and 500 units for P Read, and a 500 for a 'Mr Minter'.
Various experimental builds were detailed, including Torrington needle roller small ends, plain bearing big ends, Titanium con rods, coil valve springs, and long skirt pistons amongst others.
Build details and tests were described on the page herewith, with results on the facing page. because I have not figured out how to present more than one photo on the same post, the facing page will be to follow.
I apologise for the presentation of the photo, but when I rotated it through 90 deg. the detail became unacceptably reduced.
