Yes, I can see how you would think they might be home made, but I suspect not. I have the benefit of having the chassis in front of me and as you can perhaps see from this picture the capacitor is held between two tags which are riveted to the chassis and valve holder. This appears to be an original design feature and makes me think the capacitors were commercial items. They could have been a manufacturer-only item though i.e. made by Marconi, or for Marconi.
