... the thread about the Maserati frame on ebay kept bugging me, until I looked at it again, and finally realized what was tickling my hind-brain..
That frame looks a lot like the top-line Sutter frame from the 70s...which was made by Olmo, and as I think about it, I vaguely remember something to the effect that Olmo made the Maseratis too..
