I don´t know if this could be helpful but Simon from Convoy might at least have a deeper knowledge or even some contacts to possible factories since he designs his own flashlights - they need to be build somewhere…. Our valued BLF user J-Dub74 seems to have a direct connection to him.
At least Simon has a good knowledge about how a flashlight should work, and his level of flashlight making is about what we want: very decent quality for a budget price. But I would expect him (like Supfire did with the M6) to come up with his own design of the concept 4x18650-4emitters and not copy the SRK looks. I would not mind a fresh design btw.
Simon sells Convoys, but Convoy is not an OEM, Dipper is another name for the same lights for example.
And well Simon is not the most responsive of guys, has health issues and is working on the XHP light now
If we can find a OEM that is making the SRKs now design wise it would mean making the threads square, adapting the inside of the Head, the rest of the housing would be UB their computers already.
Should take less time to adapt existing CAD models and load them up to machines capable of working with the exact size chuncks of ALU we need then starting from scratch right?
Not reallly, yes Simon sells lights that are/look the same as others. But he has some original designs and lights.
He designs them and makes them (= he is controlling the proces) As seen before, Simon could design an entire new light and make it, and he might be able to do it within a couple of months.
But as you said, he might not be in the mood to do it right now.
