Unknown Benford Roller

[Gadget]

Hi everyone hope you’re all alright, I have recently acquired this Benford roller and I can’t find anything about it all I know is someone has removed the whole clutch system for it to vibrate and lost the belt.

Any ideas what this roller is and if parts are available would be really appreciated.

Thanks for any help in advance
