A S Gillott - L'Atlantique (I think)

Thanks @anidel and yours is very nice also.

I have emailed Mark and provided him with numerous photos and he said -

A remarkable find. With all its original,parts and unmolested. All the nuts and bolt heads look crisp and Unchewed. The frame was built as a stock frame in 1951. They put the year as suffix on stock frames. Because this one has chrome I am now of the opinion they held the frames unpainted until a customer chose the finish. In 1951 there was a nickel and chrome shortage due to the Korean War. Maybe that's why it had to be overpainted due to a thin layer. It would have been chrome all over do you Think?
The chainset is a Gnutti cotterless type with a splined axle. The left hand Allen bolt will be a left hand thread. They are difficult to get off, needing a special extractor, Gary Higgitt has had some made. The chrome on them looks good and is recoverable. Saddle is lovely as are all components, good quality and typical,of the period. Even the tyres look usable. What make are the rims? Chain and sprockets show very little wear. You could oily rag it, new brake blocks and tubes and ride it as a very original ratbike.
