What a magnificent plant!
Piltz has seed from that area, his own collection, but probably close to where ML369 comes from.
Aymeric de Barmon's website has noureddiniana ML038 seed listed.
An ebay seller - Fineorangeman shop - has a M. noureddiniana from a Rogozinski collection. He has previously sold a ML369, so might be worth contacting.
Good luck.
