IH or NH 50 self loading round bale wagon

[Farmallfarmer95]

Howdy, today I purchased what I was told was a new holland 50 self loading round bale wagon. After doing some research I realize there isn?t any pictures, manuals, or even information on these. So I?m wondering if it?s an international 50. (Still no information or pictures on these). I was curious if anyone had any experience with them as well? And how they work exactly. Do the bales lay back on their side when unloaded or do they stand upright like they do when loaded on the wagon? Thanks
