The unit worked and was stored.  When turned on now, the unit comes alive but belts slip.  The cassette caddy (see pictures) has broken clips so it can't be used very well.  Unit played tapes without the caddy.  Complete with imitation leather paded carrying case, shoulder strap, factory service manual and original user manual.  Power cord included and unit will run on standard 'C' cell batteries.  The electronics are good and the heads are not worn out.  There is another Ebay listing 125488407252   for a C-104, and the casette caddy is the same if someone is wanting a full restoration.  Belt kits are found on Ebay listing 255382202108 and elsewhere on the web.
