I have fitted a lot of Devon Rim full price rims and they are absolutely excellent without exception. However, when I have asked for spokes which match the specifications in the Ariel parts lists I have been told that they only supply spokes to their own specification - which can and frequently do differ from the Ariel specification. Whilst I am aware of one Ariel parts list specification error, (fixed rigid rear wheel, 1948 Square Four), on the whole, I retain the view that Ariel knew more about the best specifications for their spokes than a modern supplier ever can do.
I have had a telephone discussion with Devon Rim's manager (who had bought the business a relatively short time beforehand) on the discrepancies between Ariel spoke specification and Devon Rim spoke specification. It was made entirely clear to me that, in his view, Devon knew far more about spokes than Ariel had ever done.
So, I buy my rims from Devon, but my spokes from Central Wheel who willingly supply spokes to whatever specification I want - which is Ariel specification.
