Wiring loom identification...

[sandman]

I've come across a repro wirering loom that I'm having troubles verifying it's origins.. The loom in a braided repro loom - black-clotch with blue tracer... the loom is for alternator and the alternator socket is white. The lable on the sealed bag reads -326 ALT I assume the loom is for a Mk I Cooper S

Anyone know who might have made it?

sound like an Autosparks one to me!
