Hi Jan,

We've spoken about this before, but now I can air my thoughts in public (and someone can correct any mistakes in my logic). The bb info should place it about 1961 to 1964 if the story is true. The rear deraillieur spring hole should also place it early 60's (wasn't it 1963 for this one?) The front brake reach being shorter than the rear is consitant with the period (Universal 61's were packaged as sets quite often with a shorter reach brake).

The stinker is that the lugs are the earlier style with the projections (ears) on the side of the lugs that wrap forward around the headtube. My money, though, is that the frame is between late 1962 or 1964.
