Agreed, it's like an AW Mk.II (I don't remember offhand if it's just a renamed AW N.I.G. - apologies for that). Have experienced a bajillion of them on the retired Spin Gen 2 share bikes I've worked on.
Also planning on mounting one in place of a rotary Sturmey hub in one of their 90mm drum brake shells. Should be fun; I believe it's a drop-in swap.
