Correct fitting for AGA Divator FFM hose

[zwitter+]

Hello learned divers

I have purchased a Divator Full Face Mask. It has an odd fitting. I believe it is M16 x 1 metric thread. Not what my Scubapro has on it.

Does anyone know who or whare I go to get either a hose with that on the end or an adaptor from this to the normal imperial fitting nearly every other regulator uses? In my case a Scubapro MK25?

Thank you
James
