Nick,
Wow!

Your 1/4 ton amphibian sure looks like it has been in and out of the water more than just a few times.

The weathering and rusting is excellent!
My models really looked like toy models of the real thing

and not at all realistic looking as your model looks when I first started building back nearly 40 years ago . . . LOL

You are off to a great start. Keep those models coming!
