1775 x 1 . Boot Actutaor For XK140 and XK150 models. A cast alloy Striker (actuator) for the  Boot Handle Button (actuator For 2376 & 2377) that operates  the boot lock butterfly wings. This is an arrow-head design with square socket and pin fitting for onto the end of the key barrel.  Original Ref. BD15590A. Original Number BD11265A

NOTE : Depending on how wires are set up (or stretched), it is often required to file the striker sides  to be  thinner with a curved leading edge, to sit clear when at rest. It then needs to descend and force open the 'butterfly'  pivot lock upon the push operation, to release the spur wheels. SEE 2376 or 2377 for further detailed setup advice.
