I've got a set of DiaCompe complete with levers and hoods. Similar(ish) to the early 600's you've shown. Reasonable condition. PM me if you're interested.
Mine are nut attached so unsuitable I'm afraid. They are very similar to the Golden Arrow ones above.
I have been toying with turning up some aluminium 'sleeves' similar to an allen key 'nut' but without threads so as to fit nut fitting calipers to allen key frames. Just need some 1/2" aluminium rod.
