I've seen a few mentions of the 12/50 on the Web, but only a few. When
was it brought in? Not that I am desperate for horsepower, but a
little extra could come in handy...

15% increase in power, for very little effort. Sounds worthwhile to
me!

But would I be able to handle such a powerful beast?

I am less concerned with going very fast than I am with having a very
pretty four-seat convertible to drive the family around in. If I see a
car I like, for a price I like, and it has the single Solex, I shall
certainly drive it for a while before deciding whether to upgrade the
carbs to HS2s. I dislike the idea of engine transplants and such like
on a relatively stock classic.

That "only" worries me...
