Hmm I should've removed the grease first before taking the photo but yes @7ven it's a Lytaloy headset, these frames would have been fitted with a such a headset unless specified without.
Thanks @jeff80 me too, I bought them from French eBay on the cheap and then got Paul from Harry Perry cycles to retap the French threads into English, which is a fairly straightforward process as an English pedal thread is slightly larger.
