I've got the Special Lubrication kit with the red-capped Tecalamit guns in it,and I've also found a few red capped guns which I've bought separately. There are two places of manufacture for the guns. England and Germany. Only the German ones are red-capped and say Made in Germany on them. The English ones have metal caps.
Only the red-capped German ones are in the Special Lubrication kit, unless someone has cobbled a kit together, to the best of my understanding.
