More vintage parts to ID, please help!
 

Hi everyone, found a few more mystery parts. If anyone can help ID these parts that would be great!

1. 2" wide double ended black hose? Multiple connectors, maybe GI Joe?

2. 1.5" tall motorcycle front forks. Thought it came with a GI Joe mini vehicle but it's not GI Joe.

3. 1" Tall red oil drum. Thought it was A-Team but it's not.

4. 3.5" wide orange/red double barrelled cannon. Has a scope and metal pin that enables it to move up and down. It's larger scale like a Mantech figure. Don't think it's Mantech though. Attached top and side photos for this part.

Any help is greatly appreciated!
