That is a bit weird. It implies that they ought to be connected in parallel. So why not a single 2.5uF capacitor?
Aha - W197 was a Hunts part number, available in values up to 2uF https://www.americanradiohistory.com/hd2...e-0015.pdf
Further on page 128 here http://www.commsmuseum.co.uk/communicato...201960.pdf it says that in 400V the maximum value was 1uF - so to get to 2.5uf at 400V needed 2 x 1uF and 1 x 0.5uF in parallel.
