Wanted: 40-hole chrome or stainless rim (27" x 1 1/4)

[Trollface]

I've been trying to get hold of a 40-hole rim to build on a tasty old Sturmey FG4 dynohub I found. I was hoping to find one in new old stock somewhere but so far I've not been successful. Most shops I've spoken to have said they'd like to get hold of the same part too. Does anyone know of any such rims that still exist? Any leads you can give me will be gratefully received!
