No. 246 Green Chevron
This pen is from the personal collection of Joudenali. Watch out for reviews of truly rare pens from his treasure chest!
The Spanish 24x models were available in a blue, green and red chevron. Interestingly, it seems that sometimes the chevron coloured Spanish pens were covered with plain black celluloid paint. The prices of the black and coloured pens were the same, and so I assume that the Spanish manufacturer had no problem coating coloured pens with black if the latter received more demand and coloured stock was just laying in the warehouse.
