Here is the finished product.............
This is the Iron Shipwrights' Resin 1/350 PBM-3 Mariner that came with the USS Mackinac AVP-13 Small Seaplane Tender kit. Jon also sells them separately and he has PBY Catalina's too.
I replaced some of the supports for the wing floats with brass rod otherwise it is out of the box, with the exception of the propellers. (there are no props in the kit) I also add brass rod for the machine guns.
Thanks to Jim Baumann for his fine examples of small scale flying boats and their water effects. I have used his water mist technique, here.
The water is Plastruct's "clear choppy water" plastic sheet that I spray painted the top of with Model Master Dark Sea Blue.
