Alessandro Muzzle meter??

[arfy]

I got a used Muzzle attenuator and I really like it, not perfect perhaps but these Express knock-offs we're making are pretty loud, aren't they?
But the meter in the Muzzle has never worked and I'd like to replace it, if for nothing else but to see what it does.
Does anyone have an idea where to get this part or at least how to identify it? I can't see any markings on that give a part number or anything. I'm looking at all the Xicon meters in the Mouser catalog and I don't really know what I'm looking for, I suppose I could try contacting Alessandro, there's no email address I can find on there website though.
