Brian, I have adapted all of my large format lenses to use 67mm filters. That way I have one set of multi-coated filters to carry. There definitely plenty of Series VI filters around

Paul,
I adapted a 52mm stepping ring to the series VI threads on my slip-on adapter for my Ektar 203mm lens. I had one machined, but you may be able to find a Series VI to 52mm adapter ring somewhere. Or, you can take an old filter ring (without glass) and file the male threads and glue it into the Series VI threads.
This has two advantages: 1. You have a lot more, readily available filters to choose from. Plus you may be able to use filters you already have with a 52mm stepping ring. 2. You don't need the retaining ring to hold in your filters, making mounting filters much less fiddly.
Best,
Doremus
Just a note for anyone finding this thread in the future - in the UK (and presumably the EU also) a version of the 203mm marked 'Mount 370' is common (I think this was made in the UK). It takes a range of push-on accessories (filters, hoods), similarly marked as '370'.
A quick google for 'mount 370 ektar' and selecting 'images' should give you examples.
