Lynx II, hull # 4225

[Bruce Parker (RIP)]

The Fox (and Otters) have a square metal shield on the exterior hull hatch over a 1/2" stud that works on a lever from the inside. 'Gerry' couldn't open the hatch (or any other) unless he had a special tool with a 1/2" square socket. The metal shield is made in such a way that a tab/handle in a crew members pocket would easily slide in and open the hatch. I expect the vehicle crew would each have an issue handle in their battle dress pocket. I use a screw driver with an inverted 1/2" socket welded to the end as my 'key'.
