Well, something is very wrong with this drawing. I don't think, the tail section made of light alloy would survive the engine exhaust.

Then the warhead diameter is given as 1' 3", i.e. 381 mm, while the PC 500 RS had 300 mm diameter.
Then the combustion chamber construction looks very fragile in its forward section.
But the fuse components are designated with "Bl", so it's a blind bomb anyway - and there's no engine igniter present in the drawing, while it's socket seems to be plugged with the steel rod running through the combustion chamber.
