Calico 950A Measurements?

[Neon Sentry]

Does anybody have accurate measurements of the Calico 950A and its 50 round magazine? I can't find any repro/airsoft versions; hardly any reference images either.

As far as I know, it's the only identified found part (aside from the AK mag) used on the hero "Weapon Arm" from RoboCop 3.

I am also searching for any manual for the Calicos, so i let you know if i found any.
