Group shot to date:
Head sculpt/Eye colour differences:
There is a definite difference between the Made in Hong Kong figure, On the left below, and the other variants I have collected. The eyes are narrow and the sculpt appears to be a bit 'Sharper'. There are also differences in the eye colours.
There is also differences between the satchel colours. The PBP figure has a much darker bag as can be seen here in the middle.
Looking for Toltoys/Harbert Boxed Landspeeder....
