Ther is a certing mercedes resource company saying "German made for us by
Wolfswerke-sachsen ( by same company and same nozzle that was formerly branded as Monark). Yes! We brought them back..."
I can't remember the Monark nozzle number that I used in my 84 300D but in post #13 a member claimed he used Monark "261's."
