Hi stuart ,
That's a really cool looking Seahawk ; It's just a guess but is it a Hasegawa kit .
I have 3 1/72 scale Hasegawa SH-60 Seahawk kits in my stash along with 3 Italeri Rescue hawks .
Someday soon I hope to getting one or two of them built and I hope they can look as good as yours .
I also like the panel line detail and weathering , I was wondering if you had any construction pic's of the scratch-built sonor bouy station as I think it really makes the Seahawk look complete .
Well done Stuart
Kind regards John
