Gun and missile ID help please

[GoktimusPrime]

I was recently at my parents' place and foraged some old stuff of mine, including some old TF accessories. Among them I found two things that I can't quite identify...

1/ Chrome missile -- who does it belong to?
2/ Gun. It looks like Blitzwing's rifle but it's a different colour. It is NOT Overcharge's rifle because I moved out of home three years before Overcharge came out. I've never owned the Diaclone version of the toy and I don't know anyone who has the Diaclone either. So how the hell did this come into my possession?!? (o_O)

I don't think it belongs to any other Transformer does it? I got my Blitzwing 2nd hand - from a friend who decided he'd "grown out" of Transformers and gave it to me. It was a very long time ago so my memory about which accessories he came with are a bit sketchy, so I can't remember if he had a purple gun or this gray one. Weird huh?

Anyway, here's a pic. The gun on the top is Overcharge's, whereas the one on the bottom is the mystery gun. Overcharge's gun is cleaner whereas the mystery gun shows some mild aging. The mystery gun is also a darker shade and a 'sharper' sculpt.

Missile looks like g1 grimlock

As Sharky pointed out, it's definitely Grimlock's missile:

Just be aware that there are two versions, stumpy missile (like in the link) and long-pointy missile like you have.

It'd say it's probably a gun for a KO Blitzwing, but the only KO I can find is this oversized one. There was a white Diaclone version, but the source is unable to say if it is legit or a KO of the Diaclone toy.

Top gun looks of better quality than the bottom one. It's possible the top one is legit and the bottom one is not.

That's weird... I've never had a KO Blitzwing before, so how the hell did I end up with a KO Blitzwing gun?!? (o_O)

1AZRAEL1: The top gun is from e-Hobby exclusive Overcharge, so it's definitely legit. The bottom one is the gun of mysterious origin!
