WTB : Family Computer Robot Block Set Blocks, Stands & Hand

[Great Hierophant]

I have a R.O.B., but I am not so sufficiently wedded to the light/dark gray color scheme that I would spend a lot of money seeking out "Stack-Up" parts.  The parts for Robot Block are identical save for the color.  (The same cannot be said entirely for Robot Gyro).  So, anyone have a spare set of Robot Block parts which they could let go?  I would need both red hands, all five blocks (red, white, blue, yellow and green) and the five white stands.  I do not need the cartridge, manual, tray or box.
