That armored gerwalk is sweet, the last link Carl put says it's a semi-custom so it doesn't sound like a production kit and therefore I wouldn't put it on your list. Just like all the GPB customs, the 1/72 VA-3, the Thunder Hammer, etc. All custom builds and not ever offered for sale as a production run.
Doesn't appear the ever was a 1/72 Switchbalde 19 either.
