Ok, despite numerous attempts to try and get my hook numbers to make themselves more legible to help with its i.d, including members suggestions, i have failed miserably and given up. But, what i have done is gone into Duxford and, with the kind help of a member of staff i’ve taken some close ups of their Gannet ECM.6 and Seahawk FB.5 arrester hook beaks.
After studying them all i’m still none the wiser as when viewed from above where the hook attaches to the arm, mine has an extended part of the casting before the threaded section, but the other two don’t appear to have it.

A completely different type perhaps, or maybe somethings been altered or is not original? :confused:
