This is the RWD 7.
The seller pretend it can detect any Vg-2/Spectre , shuts off for 5 minutes,

Anyone has an educated guess of his true value ....they claim
to be above V-1 or Sti .....I have some doubt.
The site in french :
Cost 300 euros.
I found also this site :
I believe it is a Marahuma 705X from Japan ...looks huge on the dash
