Stop Press: Whole of Caterpillar bought by BIC pens to produce hard wearing roller balls. They are to produce a special Claas line in Omaha with green ink for the European market and yellow for the States and Australia, features to include special rubberised grip for better traction!! Pen production to be centred there for a while due to import duties imposed on EU produced goods (no change there) and to use up all the surplus plastic from tractor and combine production(source Reuters and AP). PS Only european designed pens will be made as american design did not have desired output!
