Some good info to be had in this article.<br /><br /><a href="https://www.classiclightweights.co.uk/classic_designs/rotrax/">https://www.classiclightweights.co.uk/classic_designs/rotrax/</a><br /><br />The article, to me, sort of explains the thinking behind offering a track frame featuring a drilled fork and brake bridge. Rotrax moniker was a combination of road and track and many of their customers would use the track frames for both track racing and training, even fitting them for mud guards, etc. Brakes would be very helpful on the roads, and nowadays are required in most places in order to be considered legal.<br /><br />I think it is a nice frame and it would be hard to buy one of comparable quality, with lugs, for less than $800.00 today.
Edit: This verbiage might help on dating the frame:
Frame Numbers
Rotrax frames are easily dated and identified – they used a small stamp for the numbers which were neatly punched round the bottom edge of the bottom bracket shell. The first two numbers eg 51 denote the year in this instance 1951.
