Note the wingnuts on the front hub. This along with the fender attatchment braze-ons adds to the Clubman suspicion. Photos of the cranks are needed, 1948 clubmans came fitted with a 3 pin 46 tooth chainring. One last thing, if the hub is original, what cinches the ID is if it is an AM hub for '48 models and an FM for '49.

That rear brake cable is begging for some top tube cable clips. Velo Orange sells them: http://store.velo-orange.com/index.p...ing-clips.html
If you are looking for a period look, a Fulcrum clip and a pulley would do nicely.
