While I am not going to take the time to scan the individual stencils from the book itself, I will link where you can buy the stencils I've found to be commercially available.
This is also a wisteria stencil, pictured on the back cover of the book, that is also available from The Stencil Library, #66.
On page 84 there is a rose border that is TSL TR117.
This is a thistle border shown on page 82 with a slightly different edge treatment, but the flowers are the same. The Stencil library sells it with their number 76.
This is, of course, the stencil pictured on the front cover. It is offered as #74.
There is a dandelion border design offered on page 37, it is #78.
On page 57, there is a nursery frieze of marching soldiers; it is #116.
And here is another nursery border also on page 57, #104.
These rabbits, sold as #105, appear on page 62.
There is a rose border pictured on page 38, sold as DE 29.
There may be more available, but those were the stencils I recognized. I really appreciate having a readily available source for period designs.
