Another recent conversion, but not from 700c...
It's a Westland, the frame was originally built in 1958 by a small framebuilder/shop that was based on the south west coast (England) just down the road from where I live.
A very little known builder, especially beyond the local area but produced some frames of exceptional quality from the late 1940s to the early 1960s, this one has some lovely custom, filed and reduced lugs and near perfect brazing.
This particular one is built from double butted 531 with 531 round blade 'track' fork legs and the entire thing is delightfully springy, sprightly and very VERY comfortable, no doubt helped by the forks and the nice long chainstays, geometry is quite 'French' and noticeably different to a lot of English club bikes of the era.
It was originally built for 590 and/or 597 wheels as many English club bikes were, but decent rims and tyres are hard to come by now and the conversion to 650B is very easy as the extra brake drop required is very small so it now rolls along on some modern Pacenti Brevet rims and Compass/Rene Herse tyres.
