Perfecta 6mm Value?

[B]

I wasn't sure where to put this, considering where we stand I didn't think anyone would mind.

I have a "Perfecta" 6mm blank gun that could be called VG or VG+ if it weren't for a significant chip at the muzzle. Comes with 50-60 blanks. I cannot find a good reference for value, can anyone give me a good ballpark? I am guessing not much.

Nobody has seen one of these before? An old auction in Australia is the best I can do, not exactly relevant. I have no use for a noisemaker and I want it gone.
