Help ID vintage toy parts!
 

Hi everyone, if anyone can help ID these parts that would be great!

1. 3" long black robot gun. Looks like Transformers but can't find this gun on the transformerland site.

2. 4" long red vehicle part? Looks like something attaches to it, the long black peg moves the black fins at the back. Also, looks like something attaches to the red pegs on each side. Thought it was Thundercats but it's not.

3. 4" (when flat) hard plastic belt with holster and loop. Thought it was A-Team but it's not.

Any help is greatly appreciated!
Jeff
