Thanks Christopher
Unfortunately I do not have dimensions.
Yes, you right, it can be Chuuzao size instrument.
The koma is bamboo and looks like tsugaru as well.

It might be re-purposed minyou shamisen as well like the one here:
On the listing it mistakenly marked as Hosozao.
Owner has no idea what type of the instrument he is selling and he says so straight forward
