Brevettato Choke

[administrator]

I bought Barrie Bird's gas flowed Weber 38DGAS carb for my ME last year and it came fitted with a Brevettato manual choke conversion, which works very nicely and is a lot neater than the 'bent tin' ones generally available.  Barrie had no documentation on this and I have been unable to find anything at all about it - a Google search returns nothing relevant.  Does anyone know anything about Messrs Brevettato?
