This is great, I've only just seen it!
Thanks, superb craftsmanship on the frame.
Your chainring there is the outer ring
OK, had a look at a load of Stronglight 49 images and can see what the previous owner has done now - another ring ordered to make it a double.
You probably know this but the chainring in the picture is off
Thanks, didn't know/realise that but have now figured out what you mean and this is how it should look?
Previous owner also didn't have the correct dust caps and fixed them in with blu tac.
