Thanks Non-Fixie,
I was originally looking for a frame to build a single speed but when I found this I thought it was worth rebuilding to original config. I agree that it is more of a tourer. I wouldn't be a fan of those bars, I'd prefer to keep it drop bar.
I think the only component I'm missing is the big chainring but seeing as it's going to be a town bike the 42t will be fine so I may just build it as 5 speed initially.

I also need to replace a few spokes on the wheels. Should I remove all the spokes and get a wheelbuilder to rebuild the wheels with new spokes? Or should I just replace the 4 broken spokes?
