Yes, one of the first model kits I owned as a child. I got it for my birthday, less than 10 more than 7. I figure that because the kid that gave it to me went to elementary school with me but was sent off to boarding school before we went to the school that held 4th & 5th grade. I ran across the reissue the other day at an antique toy mall my wife like to go to. It was issued in 1971 when I would have turned 7.
I snapped it together rather quickly like I would as a child but painted it by hand with some cheap acrylic paint I bought at Michael's. I used the same color (Camp ground green) as the plastic and bought a lighter green to do the belly and spinal ridges. As a kid, I didn't paint the body, but I used Testors gloss yellow (the type you got in the multi paint set) to paint the eyes, belly and spine.
I am trying to replicate what this kit might have looked like after I built it 40 some odd years ago, but with some differences I would have done if I had the proper supplies and materials.
