Designed and sized for the Hobby Boss cockpit
This is a set of two individually detailed Martin Baker Mk. GRU5 seats in 1:48 for A-6A, EA-6A and A-6E Intruders (used until about the mid 70s, when replaced by the GRU7), designed and sized for the Hobby Boss cockpit. I can't say if it will fit the Revell EA-6A.
The belt and hose arrangement is different between the two seats. Includes a pair of drogue gun activation rods for each seat that attach to the cockpit tub.
