I think this link might be useful and interesting; I was looking for BPF Wildcat schemes and discovered this website. Not a ship guy, but I found this a very interesting read and a wonderful photo chronicle of life aboard an RN escort aircraft carrier. Attacker was evidently built on a C3 merchant hull, and was originally to be named USS Barnes in USN service, but was transferred to the RN under lend Lease. A very active ship that saw a lot of action- a shame she couldn't have been preserved as an example of her class. I hope you enjoy looking at the photos. (How about those Swordfish flying over NAS Alameda?)
