251 ?

Shall we start to talk like adult people?
There had been 2 different T251, one of them with a shorter wheelbase and different suspension. Both had been tested at Reims in order to find the best option for the race. Some sources even talk about a 3rd car, as photos indeed show 3 different versions. However, it may be that this was the prototype which then had been converted to car #2 or #3.

The stories about the Bugatti mechanics cutting the chassis down in length just before the race are nonsense.

I didn't wrote this, I only said that there had been 2 cars of which one had a slightly shorter wheelbase. And both cars had been at Reims simply because there had been different cars with the "28" on them.

However the story about two different wheelbases came about because someone wrote that one car had been modified in a panic before the race.

What I have in my notes - do not remember the source - is that when the prototype didn't performed as expected they built a 2nd car with a slightly shorter wheelbase and changed suspension. Thus no modification of a existing car but a complete new one. No idea whether this is correct, the T251 is not my "normal business".

Fact is that there had been 2 different cars, both present at Reims, and both with race number 28. Which obviously was the background of Udo's confusion.
