Using Raytech Tumble Twin

I was given an old but unused Raytech Tumble Twin TT-5 model 3016. I
can’t seem to find any online about this model and what
it can do. I need a tumbler for polishing finished jewelry that
contains silver, copper and brass wire, beads and stones, and chain.
Does anyone have this tumbler and if so, can you tell me if it can do
finish polishing? The "barrels"are yellow plastic tubs with lids and
are tilted towards the front of the machine at a 45 degree angle,
which is much different-looking than the TV-5 model.

Thank you,
Olivia
