Oh right - yeah, good catch...  I've fixed it in my branch. I guess I
was trying to utilize the common ModelTypeToString which vectors off if
type is right...

Thanks for looking at it from a ccw/s390 perspective - I was mostly
flying blind with those. I can "see" the proper syntax, but didn't have
something to test with.
