Dinosaur Tank (恐竜戦車 - Kyōryū-sen-sha) is a monster that appeared in the TV series, Ultraseven. It appeared in episode 28 not sure of your particular make/model but its cool regardless!
I have a larger one by "Tsuburaya Communications" or something like that, not sure if same company because they have different headers
Damn, that is a nice one. I was after the one Ricky had for sale eons ago. What a find! Congratulations on a keen eye and your luck Greg. They also issued him in gold, and I think maybe another colour, but can't remember for certain on that.
It says "Not for sale" on the bottom, so this may have been a promotional or internal gift only of some sort.
Micro Dino Tank by The Moog Image Dump, on Flickr i bought the one from Ricky and love it . . . he told me he had a brown version that matches his standard sized one.
These were a "gift" if you bought a certain figure at an event years ago, I didnt get it then as I didnt want to spend $60 on a toy I didnt want just for the mini. But, I got lucky a few years ago and walked into Mandarake and they had a few of each color so I was pretty happy to say the least. That is one of my favorite all time toys, so small and so cute and it rules. My cat is happy too. dino_tank_2 by Baikin, on Flickr
I think that is by Bandai? Mine is also a larger version but by Tsuburaya Communications as well and more "cartoony" Now I also need one of the minis
The big one was also made in a heat activated color change vinyl, it would go from brown to orange. I still need the two regular colors, I used to see them all the time but theyve dried up recently.
