Roto Jet that Cyclops!

I adored the little silver accessories like these from the Major Matt Mason range.

I especially liked the rifle at the top.

It was only as an adult that I found out it was a miniature copy of the mighty life-sized Lost in Space Roto Jet Gun. What a toy! I would have loved it.

Turns out too there were more like this, especially in Japan, who seemed to really go for the style of rifle.

 Did or do you have anything like this?
