There is no obvious origin to begin with, but i can move the object to the origin.
As i can't determine the proper scaling i defaulted to millimeters.
And i did not bother with UVmaps as this is a sample object which i will most likely replace later.
Edit: preview fixed, still not sure about the scale
Edit2: i tried different scaling and i think i hit a usable ratio
