I just spoke to Neil and he is confident that they can replicate the original hoses almost exactly - the only missing bit being plating on the new steel pipe. That isn't really a problem though as it can be easily painted / protected.
I understand his rationale for wanting complete hoses to dismantle too - as suspected, getting precise dimensions and union orientation is important, as is removing the crimped junctions without damaging the unions which must be re-used.
As I mentioned, I have a complete set of intact hoses for precisely this event so I can get those sent off and we can see what they can make out of them
