"Northern Arrow" - Original Propeller Design - Something Quite Dodgy

The original propeller design for Mr Hall's Northern Arrow 4oz Vintage Wakefield leaves very little to the imagination but might prove beyond the ability of today's vintage modellers. What do you think?

This is a scan taken from the original Northern Arrow plan of the propeller assembly and it's associated instructions. Even in the enlarged images it is hardly legible.

And here is a negative of the original scan reworked through Photoshop to improve legibility. Instructions were, I thought, very concise, if not a little dodgy.
