What are these #2

[Pumpytrilly1]

Can anyone please help me with some more parts?

I assume the sight rail is automag?

Vaguely remember the grey expansion chamber is for back bottle guns?

Much of the pile of stuff in the middle looks to be for a stingray.

Is the site rail 1" ID? If so, it is for a mag.

Sight rail looks like a VM to me.

Sight rail looks a bit large to be for an Automag.

If its not a mag site ,then its a VM68....

I think you guys are right. Definitely wider than an inch. It has set screws?
