1. That is not a 3Rensho product. It's not even Japanese.

2. It's definitely Italian built. Mid-size factory; not an
artisan builder, not Bianchi etc.

3. I do not know. It is the same shell Basso used at one
time. Could possibly be a Basso but I do not know that.
Either he measured poorly or it's not a Basso as the
geometry as listed makes no sense:

Mid 1990s Gap used that shell, after the one with the panto
"B" logo was dropped.
I don't have an upside-down Basso snapshot and a web search
was fruitless.


Here's the matching shell on a 1990 Basso Gap. Other details
differ, though: brake bridge, seat cluster, etc.
