Centurion Collimator Jettison Switch

[Lauren Child 12]

Any ideas what the jettison switch on the Centurion collimator is used for?

no idea but it sound interesting

I'm half expecting a james bond type ejector seat answer

Jayne Bond here: A guess that it was to set off the explosive charges to release the towing point bolts of the mono-trailer from the hull rear. Why put there on the collimator I know not. This also implies that I don't know where the switch for performing that delicate task was! Yes, explosive bolts and a 200 gallon petrol tank!

A collimator is a boresighter.

The collimator in this case is (if I'm right) synchronising the sights between commanders and gunners periscopes.

External fuel tank was my first guess as well, but the cables don't seem to go there, hence being a bit stumped.  The cables run + to - via a fuse, and into the collimator itself, which only seems to connect to the turret.

No ejector seat found in the turret so far....

D'oh silly me.  That'll be an explosive fuse on the wiring diagram, not an electrical one.  

Thanks for talking sense BlueBelle, Ive been spending too much time on wires

It's not a wreck, it's a beautiful butterfly in kit form.
