Just curious since I haven't ever seen one, does anyone have a drawing of the standard BSA A10 type gearbox in cross section as assembled they can post up? I have various exploded views and also the cross section drawing on page 54 of George Prew's Gold Star book. George's drawing is of an RRT2 with needle roller layshaft instead of the flanged bushes of the standard box.

P.S. My Rocket Gold Star 'Carlsberg' replica rebuild is now finished after 10 months of extreme highs and lows, so I'll post up some pictures soon. Scared myself when I added up the cost today but it was great entertainment value and hopefully will pay me back in spades with great riding.
