I have a few Bozzi lugsets in my collection. I have placed pictures on Velobase.

Because Emilio Bozzi owned the companies Legnano, Frejus and Wolsit, they were often found in these bikes. They were offered for sale to any other company. I think the crude blancs were produced for more then 30 years, before the War. Patterns cut from the nozzles varied througout the years and give different looks, but the raw lugs were hardly changed.
