What a fantastic thread. A pal sent me the link so I joined the forum just to post here.
I've been trying to get information on Rory O'Brien frames for a couple of years now. I inherited my dad's fixed wheel machine when he died and I've since restored it. Would love to have some transfers for it - any ideas anyone? - I remember when the bike was new, it was black with a gold 'signature' type script on the downtube. As far as I remember, the frame must've been built in '62 or '63. It was built to my dad's own spec, including angles and the split seat tube - a feature he'd allways wanted on a bike since he saw a similiar frame when he was track racing in his youth. It's got a really nice Stronglight headset with a 'toothed' adjusting system. Anyroad, here's a picture of the frame. (if I can manage it, that is)
Now I've joined, I may as well make the effort to join in on the rest of the forum, but it'll take a while for me to explore it.
