I have an old f1.4 black paint Summilux. With it is a two-part lens hood - a 12504. I have been told that it takes a Series VII filter (whatever that is) and it fits between the two parts of the 12504. The hood part unscrews from the clip-on-lens part.
After careful measurement with vernier calipers, I conclude that I need a filter with outside diameter between 50.1mm and 51.1mm. With the two parts fully screwed together the filter would need to be 3.1mm or less at the rim, though if it were a little thicker there is enough thread to cater for a rim thickness up to, say, 4.0mm.
Note that the filter is captured, it needs no thread.
So where do I find such filters? If they are common, what is their "standard" description?
