• @clubman thanks for the info, I'll leave it to the professionals this time :)
    @falconvitesse I think you are right, there are a lot of similarities with this bike https://www.flickr.com/photos/makfreak/albums/72157673127814544/with/31237905546/ which is original paint and has matching rear dropouts. I can't quite see the front, but I don't think they're the same as mine, although I'm almost certain mine are original to my frame. No need to change them and no one will be looking / able to see them anyway!

    I got my dates on the derailleurs slightly wrong previously - it's the rear derailleur that was introduced in 1963, the front was in the 1960 catalogue. The Record group in 1960 included the Gran Sport rear derailleur. Interesting that 1963 bike I linked to had Record derailleurs, steel seatpost and Gran Sport hubs - seems a good chance that is all original equipment on mine, maybe the Gran Sport rear derailleur was replaced with a Record later in the 60s. Or maybe it was all put together in the 80s :)

    The rear derailleur cleaned up nicely, the jockey wheels aren't too bad under the grot, I'll post a pic!

    Edit - pic added here, I did have a before one of it lurking in my paraffin tin but deleted it for some reason. Grease and mud and grass all caked around the jockey wheels, the exploded pic is after a few rounds in paraffin, scrubbing, taking it apart for another round in paraffin, scrubbing and just cleaned with washing up liquid. I put the chrome bits in an Evaporust bath for a day, then scrubbed and polished with Autosol and put on some frame wax as well to try and add a bit of protection. The only bad bit of chrome loss is on the rear plate and inside where the spring has rubbed the plate. All looks ok though after being given the above treatment.
