The Energon Pub

Hi I was wondering whether anyone knew what this Transformer figure was. I found it in the loft today and cannot seem to find any trademarks on it.
Any information would be good. It look old but I'm not expert so I was hoping someone could shed some light on this for me.
I have added some attachments so you can view the.
Cheers

That would be Sixgun from Generation 1, he goes with Metroplex. His legs and arms are Metroplex's guns. Looks like he's in really good shape, too.

Hope this helps.; RPrime is right on the money.
