How many color variants of this small Wamu boxcar are there?

This one if you're not sure what I'm referring to:



I'm aware of the following variants:

Tomy:
Brown with red wheels
Brown with yellow wheels
Red with yellow wheels
Green with yellow wheels
Blue with yellow wheels
Grey with grey wheels
Black with yellow wheels

Trackmaster (all with grey wheels):
Light grey
Red
Brownish-red
Olive
Yellow
Blue
A slightly darker blue (not sure if this one actually exists or it was just the lighting in the photo I saw)
Red with "Elsbridge Ice Supply" logo and white "snow" specks
Dark blue with white "lime" specks

Anyone aware of one or more others (other than the Trackmaster 2 versions)?
