What info are you after?
The 320 series was basically SB's Utility range to the 520 and 720 series.
They always reminded me of toy mowers or lightwights, despite their claims of them being a Sturdy workhorse and sporting the 4hp BS on the Nomad.
Very basic and simple design just what you would expect from a utility.
3 models that Im aware of,
Demon 3.5 BS Base model
Nomad 4.0 BS
Multicut 3.5 BS Mulcher
Other than this, I dont know much more about the...I should have a brochure with the dates and model codes in my mess, if no one else puts it up ill dig them out.
I wont use the term rare, but They dont come up for sale often.
Others may have some in their collections and know more, but really what you see is about it.
