Hi everyone this is my first post for a long time. Here goes today I got bought a 1950's ish Rudge it has a Sturmey Archer 4 speed dynamo hub on the back. The tyres look good but the inner tube valves look like they might need replacing soon. My question is the valves are really strange looking in between presta valves and car tyre valves what are these called and can you still buy them. The dynamo lights don't work so can I just try changing the bulbs if so what type. There are oil holes and caps on the hub and the bottom bracket will 3 in 1 oil do for them. The bike looks in good condition and has all the head badges and the original bako light pump that seems to work when I put my finger over the end. It was going to be put in a skip but someone rescued it as he couldn't bare to see it get binned and I got it off him. I'VE GOT A NEW BIKE DOESN'T IT FEEL GOOD TO SAY THAT.
