Insley H875 excavator

I am looking at an Insley 875 to add to my Old Iron collection and for use around the farm. i need to know some stuff before i go look at it. can anyone tell me how much it weighs? ALSO DOES THE SWING ON THIS OLD GIRL USE A HYDRAULIC swing motor or does it use swing clutches like a crane? if anyone has any more advice or input please chime in PLEASE.

Thanks
