Going out on a limb here... The front guards and the smaller scoop profile reminds me of a DAX. If it is, it will have a DAX serial number stamped into the top of the cross member just behind the radiator. Should be right in the middle and easy to see with the bonnet up.
I had one a few (too many) years ago, and although I modified the bonnet to fit a blower, the front guards look the same.
