A common piece of kit for drag racing which locks hydraulic pressure in the front brakes and allows the rear wheels to spin for burnouts. This link shows the components comprising the line lock:

Line lock is used to lock the front wheels and hold the car on line whilst the rear (drive)  wheels rotate as engine revs increase prior to releasing the line lock
and launching the vehicle off the line.
Main feature / accessory in drag racing. :-\

many thanks, Silty and Keith,

Guess this is not street legal  :-\ or is it fool proof ?

My modern Mercedes C has electrical "handbrake", acting on rear wheels. I did not yet dare to test its functionality at 60 mph.

Any info on this particular Cobra? Chassis number? Owner's name?

Just a WAG, COX6015 ?

COX6003, perhaps...? Assuming the following forum post is accurate, the side view mirror and interior details look the same.

Agree, if the post is accurate, COX6003 would fit.

Same car but without line lock and reverse gear block ? Took the pictures during ECM 2014 close to St. Tropez.

I'm afraid you mix up cars here, Uwe; You've seen COX6003 whereas the line lock and reverse gear block is on CSX2075;

I'd say the red 289 Cobra from Retromobile 2018 is confirmed as COX6003: www.historiccars.fr/1964-ac-cobra-mkii-289.html

I'll  take you up for the beer, TTM  ;)

Just thought I'd resurrect this post to see if anyone on here will be in Rétromobile this year?
Went tonight to have a first quick look and will return on Friday afternoon until late.
