The Bugatti T102 and other post-war four cylinder designs
Part 2

Jaap Horst

After the last issue I received an interesting mail from England, clarifying the history a little bit. There have been 4 versions of the T252/3: Opening picture:T252 MkI in private posession in England, owner also has T253 engine.

T73

The T73 is the same as the T73C, differences are: cast exhaust manifold, distributor ignition, small supercharger, different engine mountings.

The T252 MkI

This was in fact half the Colombo engine, with hairpin valve springs, and 2 valves per cylinder.

The T252 MkIIa

Same block as MkI, but new cylinder head with normal valve springs, timing chain at the front. Design by Bertrand (with Bugatti since 1924)

The T252 MkIIb

New block with MkIIa type head, but timing chain at the rear

The T253

Back to Colombo hairpin valve spring type motor, but supercharged.

Some pictures:

T252 MkIIa

T252 MkIIb

Chassis for T253 engine is ready.

T73C 004, also in private collection in England.
