Not the best repair to a damaged front-end ever seen, that's for sure.
Here's one of the famous photo's of Fangio with his new B20 (did he own more than one) in front of the Lancia tower block.
And here is Fangio after crashing a B20
From the wheels on this crashed car, it seems he must have had (or had use of) more than one B20 - based on the colours alone. The wheels of the dark car are S5 or 6. The pale car is lhd, so S4 at the earliest.
Perhaps someone can tell us more about 'the Fangio cars'.
