I have found the O-rings that I bought:
20.35 x 1.78
20.1 x 1.6
19.1 x 1.6
7.65 x 1.78
7.5 x 1.5
I suspect that the two centre grooves use the same O-ring (20.1 x 1.6). 19.1 x 1.6 at the inner end and 20.35 x 1.78 at the outer end.
I had to purchase a minimum number for each size, so have many more than I ever needed, so I can send you a set or two! They differ in size slightly from what the Germans measured (and yourself) but that's what I measured them as.
