Sounds like a copy of the same drawing I have “any chance of being able to see a photo of it ?”.
My early type fin & rudder were made by TVAL in NZ, even they didn’t have drawings for the early type, so they made them using what info they had available.
I also obtained a set of blanks for the main spar, & top centre section metal fittings, so the centre section will probably be the next item to be completed, as the nosing & spars for it are done.

I’m still looking for any drawings etc for the early type of Snipe, as well as anything on the parts made by the WEYMANN or BADIN companies, of France.
