The Monogram 1927 Bugatti Type 35B Grand Prix kit.
I did build this kit a long, long time ago when it was first released. Complete with the driver, guard rail and straw bails. The plastic grass matt did not survive, it has deteriorated a long time ago.
I bought this kit some years ago again and although it came without the original box it came with an extra tire and two engine hoods as a bonus.
I still consider this as s very nice kit, but I couldn’t resist this time to add a lot of details. Fuel lines, oil lines, spark plug wires....

Some of those lines were a bit of a challenge to get in the right shape:

And I added all the brake cables too:  

The first test fitting:

And here are the pictures of the finished model. Most of the aluminium parts were brush painted as the tamiya rattle can silver was much too glossy. I used that only on a few parts. 

A close-up of the engine with some more added details like the throttle linkage: 

As I mentioned before, the kit came with two engine hoods so here is the ‘closed’ version:
