I have a 753R Raleigh SBDU track frame from 85. It's beautifully light and rides like a dream, lovely tubing and craftsmanship. The 'R' stands for race and there is also 753T which is specifically designed for track use. Holdsworth (Planet X) have actually secured a limited run of 753 to build their new top of the line frames. I saw them at Bespoked earlier this year and they were looking great. I'll sort some pictures out at some point.
