There is no information about the early production at their website, or at the factory available.
I was there at August 2010. Actually I drove to the factory in Blois (F) with my bike (Philippe No. 30), 600 miles in 6 days, to receive more informations.
Pictures of my bike:

I drove this bike on the l'Eroica 2009 (135km) and 2010 (195km), probably the hardest cycle marathon in Europe, opened only for classic cycles.
I can assure you that it is a very pleasant, comfortable, but firm ride even under worst conditions.

This is how I received the frame:

Weight of the frame is 1730g (56cm height), which is very lightweight for Reynolds 531 (more in the range of 531SL)
The lugs are custom made and stamped with the production nbr.

The steel bikes were handbuild by the father of the previous owner, and all old bikes and records were scrapped when the junior took over (this is what the people in the PHILIPPE shop told me). They did steel frames for other brands too, and one model was sold under their name with a slightly different lettering, but not fully matching the finest build quality of my bike:

(Scroll down for the golden frame made of Columbuy SLX; the story goes about my tour to Blois, you see me at the PHILLIPPE Shop in Blois)

They told me at the shop that my bike could me the oldest one of their brand which survived.
Another Philippe with the same lettering is here http://www.flickr.com/photos/1932125...7612358253179/

I have to add that my bike isn't for sale, and I would welcome any other information to the historic bikes of that company (which has nothing to do with the excellently made french Philippe bars), see pictures of them or come in contact with owners. You can eMail me at taunusreiter at yahoo dot de. Thanks for your interest!
