La società B.D.B. Brevetti Drusiani e le moto Comet
Si costituisce presso un notaio la società B.D.B. Brevetti Drusiani. Ha come amministratore unico Alfonso Drusiani (1905-1969) e ha sede a Bologna presso l'officina Negroni in via Andrea Costa.
Famoso tecnico e costruttore di motoleggere, Drusiani ha presentato, nel dicembre 1952 al Salone di Milano, la prima moto con il marchio B.D.B. Moto Comet, una bicilindrica con cilindri affiancati da 175 cc., alla quale seguirà nel corso del 1953 una versione Sport e nel 1954 una versione Super Sport, detta anche "Specialino", destinata alle gare.
Nel 1954 nascerà una 98 cc a due tempi con cambio a manopola a due velocità, mentre nel 1955 la nuova officina Drusiani, situata in via Stalingrado 76, produrrà una monocilindrica sperimentale di 250 cc, denominata "Pasqualino", con distribuzione ad aste e bilancieri.
La B.D.B. Brevetti Drusiani Bologna e le Moto Comet avranno vita brevissima. La società sarà sciolta nel febbraio 1956 e dichiarata fallita il 4 maggio successivo.

A Brief History of the Marque
Manufactured 1952-57 by BDB (Brevetti Drusiani Bologna)
The firm was founded by Alfonso Drusiani (1905-1969) and his sister Giannina, whose father Oreste had been a partner in CM. The firm is based in Bologna at the Negroni workshop in via Andrea Costa.
Alfonso had continued his father's business at Via Milazzo 32 where he designed and built the famed F.B Mondial 125 championship winners for the brothers Carlo and Giuseppe Boselli in the years 1949 to 1951. His proposal to the Boselli brothers for a roadgoing machine was not favourably met, so he decided to go it alone.
The first Comet machine rolled out of the factory doors in 1952, a 175cc DOHC parallel twin of unit construction housing a four speed gearbox delivering 10hp at 6000 rpm. It ran without an oil pump, using a system later adopted by Husqvarna. Developed with the help of Marcello Laurenti it was presented at the Salone di Milano in December 1952.
This was followed in 1953 by a Comet Sport with a 173cc twin in a higher state of tune (and an oil pump), and in 1954 a single cylinder overhead cam model "Specialino" joined the lineup, along with a 98cc two-speed two-stroke with twistgrip-style gear change.
1955 saw the workshop move to via Stalingrado 76 and the introduction of a single-cylinder 250cc OHV model, the Pasqualino, of which few were produced.
The company was dissolved by Alfonso and Giannina Drusiani in February 1956 and declared bankrupt on the May 4th.
Comet Models include:
175cc DOHC 1952, Sport 1953
98cc Twostroke 1954
Sport 250cc OHV Pasqualino 1955.
