I was very interested to se this post, and I have just had a rummage in my loft as I knew I had a Balilla brake somewhere. It is inscribed ‘Balilla’ and ‘Brevettato’. I bought it in the early 70s when I needed a short-reach rear brake. My local dealer let me have this Balilla at a reduced price, as he had had it in stock for many years. Here is a pic which may be of interest.
