401 bonnet mechanism

[Des]

The bonnet release cables each follow a direct daisychain route through two catches, cable passes through the rear catch, that bit you push to release, then is secured against this with a drilled metal bar by grub screw, carrying on to reach the forward catch and secured again in the same way. If you're finding the catches need pushing forward rather than pulling rearward to release, maybe they've been swapped between sides.
