Hi all,
Here's a great reference for anyone building a PBY Catalina:
Cutaway PBY at the The National Museum of Naval Aviation at the Naval Air Station, Pensacola Florida.
PBY Catalina International Association rescued a PBY that had been damaged in a training flight, restored it fully, and took the skin off of one side so visitors to the museum can see what it looks like on the inside.
It's a fantastic modeling reference!
Regards,
