Transformers Vol 1 #13 (NM)

This issue has a Transformers tale from a different viewpoint as loser and gambler Joey Slick stumbles across a very strange gun while running from some gangsters trying to collect on Slick's gambling debts.

But the gun is actually Megatron in a transformed state and Joey uses Megatron to his advantage and fixes a few things in his miserable life in "Shooting Star."
