The 123\GB-4-R-V replaces most 4 cyl. Lucas-distributors for engines in Great-British (hence ‘GB’) cars.
Note that there are dedicated 123-ignitions for Mini, Jaguar & MG.
Please check if the distributor need a connection for a mechanical rev.counter, as a 123\GB-4-R-V does not offer this.
The unit offers a maximum total of 16 advance-curves to be selected by the end-user.
Please take a look in curve table for available advance curves.
