I have a slightly bent (4mm or so out but should be fine if your running a freewheel) 36t mankind ring you can have for free, pick up near Hackney road. PM me if you want it.
Edit: I also have a joytech/odyssey clone cassette with an 11t driver built to a chrome 48h primo balance, both in good condition for £25 if you wanted to change the rear to make it easier to find a chainring to match.
