You will need a 16 tooth cog , they are the same as the ones found on the old sturmly archer three speed hubs , you will also need the locking ring to hold it on . If you have trouble finding them at your LBS drop me a mail as my LBS has them in stock . The screw bolty type things in the front wheel are skyway hub repair originals if i am not mistaken , hope this helps . ![Smiley :)](http://www.radbmx.co.uk/forum/Smileys/smilies/smiley.gif)
Not the same as a Sturmey Archer I'm afraid they are only a three spline sprokect, that is an early cassette hub with considerably more splines. You'll also need a lock ring for it too. I think it's the Suntour type like this:

But I think unless someone else has one of this type it's going to be a bit hit and miss to find what you need.
The Front hub is a replacement Skyway og kit, you could replace the nut and bolts with domed ones from b&q or somewhere but then it won't be og anymore
