How fortitutous!
I am building the same Green Max kit now and I can see how it's supposed to look.
One problem though... the basic building parts were in the kit but it appears that a couple of entire sprues are missing from the box. So the detail parts like the vents that attach to the walls and the crane are not available.
Grrr...
It's a little late to get a refund or exchange as I bought the kit at least 11 years ago... and I don't even remember where, but I'm sure it's out of business...
The good news is that the sprues with the piping and the main tank appear to be here, and that would be a key part of the industry I am building. I have other detail parts I can use, but I'll miss those vents.
