Actually.... it's interesting taking a closer look at the photo's in that guy's auction - in particular the pictures of the top of the unit when unscrewed and comparing them to mine.

I rather suspect that my unit has been repainted at some stage as there is yellow paint on the inside of the tube and the colour scheme at the front is slightly different to both other examples I have now seen.

A closer inspection of mine suggests that only the yellow has been re-done as there are some very small overruns and drips on the back.

I guess I can only sell mine for $11,000, huh?
