Hello Jim
The book is actually called
“Making Great Boxes”
and the project is called
“A box with a beak”
Within the book there are 3 pages of full sized templates, of which after checking my templates stock I find I still have all the photocopies of the pages along with the pattern templates.
Now knowing this if you cannot find the information I can scan the photo copies and the five 1:1 masonite and plywood templates for you.
If this fails to work I can post everything to you as a last resort.
I also tracked down the book, its actually with Degoose, AKA Larry so I/you can also contact him and possibly get the ISBN.
Either way a mate for the bird should evolve without too much difficulty.
No doubt Ted McGrath will have a copy of it ….spit!!
Regards Rob
