Spoke key for Brompton

[Kell]

Anyone know what size key to order for Brompton spokes?

I’ve been using one of those multi-slot ones and the size that seems to fit best is 15. But this doesn’t seem to correlate to the Park Tools spoke key sizes.

So I was wondering which one to order from the following:

Sorry, can't advise, but I clicked on the link and made me smile.

Told me it was a "Hot Product" and 27 people were looking at it. Must be all from cycle chat, following your link.

This would seem to suggest that if the 15 slot is the best fit then it's the black one (3.23mm) I should order, but it would be good to get confirmation...

This page from SJS seems to suggest some Bromptons take 3.23/.25mm - the black Park key.

But some take 3.45mm, Ice Toolz in the SJS link, red in Park.

I'm tempted to suggest couple of tenths of a mm might not make much difference, but as two sizes of tool exist, perhaps it does.
