Will Dunniway Book

Does anyone know where I could obtain a copy of the book by Will Dunniway, "The Wet Collodion Plate - 16 steps..."

Thanks!

Seems like his wife made a PDF available for download. https://www.alternativephotography.c...llodion-plate/
Please remove if not appropriate.

I don't know how I didn't see that. Thanks!

Thank you all.
