Bugatti - Bugatti Brescia T13 / T22 / T23
The Bugatti 16 valve "Brescia" was built in three chassis lengths. Type 13 was 2 metres wheelbase, Type 22 was 2.45 metres and Type 23 had the longest 2.55 metres. People refer to these three modles of Bugatti as Brescia, after the factory won the voiturette race at Brescia in 1921 in special race version T13. The chassis frame of the Brescia was from the 8 valve cars. The Brescia models up to chassis # 1611 had the plain bearing engine (3 main bearings) and from 1612 onward the Brescia Modifie had a 2 ball race and one plain bearing crankshaft, which are referred to in England as "Full Brescia". Some cars were assembled / built under licence in the UK by Crossley, in Germany by Rabag and in Italy by Diato.
The Brescia Bugatti had tyre size 710x90 in period. Blockley makes the best 710x90, a beaded edge tyre that can be used with total confidence, with excellent grip and longevity. Any cars which have been altered to take well base 19" wheels can fit 400x19 on the T13, and for some of the coach built long chassis cars a Blockley 450x19 may also be suitable. But Bugatti only used the beaded edge 710x90 size in period, and for those wishing to experience the joy (and looks) of how the cars were first built, wheels can be easily made.
