Or as close as possible. They seem to be like hens teeth, or mega expensive!

Just been browsing they have a lot of reductions, although I could not see the exact size you are looking for. Have had a couple of their stems and they have been good.

Thanks Keith. They have an 80 mm 17 degree which is as close as I've found to what I need. Thanks for the tip!
