And what suppliers have you contacted already ?

Have you tried ASNU to see if they can make you a set ?

Why specifically Siemens ? And as said, do you need high impedance or low impedance ?

Racetronix in the US offer a few 55lb low impedance injectors if that's the sort of thing you're stuck having to use
