Insley H875 Weight?

I was wanting to ask if anyone out there would by chance have any literature on the weight of the old Insley H875 excavators with the 10' stick on it? When I was young I ran one some & often wondered in later years how much they weighed? Most of them were powered with the 4-71 Detroit, although I did occasionally see them with a Cummins too. Just curious if anyone knows........... I found this one while travelling in New Hampshire a couple of years ago & had to stop & look her over!
