I wonder if we had too another Le Monstre, based on a Deutsch Bonnet HBR4, in '59 may be. Putting the two cars side by side could give you an indication of what is an american monster and a french one. Not really the same size!
The DB coach was heavily top chopped, more than the HBR Super Rallye will be later. The Monster nickname probably was referring to the strange look more than the size.
A shovel could have save many cars stucked in the sand of Tertre Rouge or Arnage from early retiring.
