You'd do well to get some verniers, or get the bits to some. The link says the bike came with a Stronglight A9 headset, which is most likely to be British, but I don't know if they made French jobs.
Is there any sign of what is fitted headset-wise in terms of make? Can you get the stem to someone who could measure it accurately? There's potential for a load of grief, but it could be standard sizes and easy. But a British standard headset doesn't necessarily mean a British bb thread...
