Additionally, NHC Naval Aviation History Branch http://www.history.navy.mil/branches/nhcorg4.htm
has several photos of PBY Catalinas in their collection. The staff can't sort through those photos for you, but you are welcome to visit the branch to view the photos and scan them yourself. A scanner is available in the branch for your use.
Also, our Photographic Section very likely will have photos of some PBY-5s. We didn't see any in their Online Library of Selected Images
http://www.history.navy.mil/branches/org11-2.htm
but they did have images of some other Consolidated aircraft posted.
So, they'll have a few images of Catalinas in their collection.
You'll need to contact the Photographic Section directly http://www.history.navy.mil/branches/nhcorg11.htm
On the Naval Aviation History Branch website, you may want to look at the online publication "Dictionary of American Naval Aviation Squadrons, Volume II." http://www.history.navy.mil/branches/org4-23.htm
In it you'll find the squadron lineage as well as the insignia and nickname.
You may want to incorporate the insignia into your airplane model. Click on this link then scroll down

If you haven't already, we recommend you contact the Emil Buehler Library http://naval.aviation.museum/archives.html
at the National Museum of Naval Aviation in Pensacola, Florida. T
hat library may have additional information and photographs for you.
