Ah, thats great thank you for the links and information. I have now also just seen one on ebay with the unpainted section and pointy bit! I think the speckled gold one is deliberate, (as the design is very consistent all the way around - and it's not a section that gets touched very often). It seems to be on the 201's that have the more decorative chrome front and back plates. Later models with the contemporary chrome plates seem to have the plain black painted number section. All interesting stuff and probably just minor design tweaks made as the years went by.
