Can you guess what this is

Saw this today any guesses what it is.

Contra-bass harp-lute? I have seen drawings of these things before, never realised how big they are. I know they are medieval.

Quick Wikipedia search. It could be an Angelique, a Theorbo or a Swedish Lute.

Some sort of ground to air defence system?

I'd go theorobo...

Cumbersome

I want to ask her how the balance is.....but i'm fairly sure i can guess the answer to that.

A friend has a smaller one, he calls it an ARCHLUTE.
