Brilliant find. Well done on the scanning too - crisp and clean and clear.
Could I make a polite request? There are many more such little publications out there, often overlooked or considered of no value, which hold information at risk of being forgotten. Many of us own a few and may even have digitised and shared them as you have. What the world needs is one, comprehensive collection...
Fortunately, when it comes to tools, we pretty much do. It's labelled as the "International Tool Catalogue Library" (ITCL), hosted at the Internet Archive - archive.org. I've mentioned it before, but it's such a useful resource that it bears repeating.
The original core of the collection was catalogues assembled by one Mark Stansbury, who was particularly interested in trowels, which were hard to find out about. It now includes much more than trowel catalogues - there are catalogues and leaflets going back to the eighteenth century, covering tools from many countries. There are over 7,000 items now, including infommercial items like your Stanley Guide.
For a longer introduction to the scope and Mark's work, see here:

Looking into more detail, there are already two items which will look familiar - this version of the Stanley Tool Guide, published in the USA in 1952:
https://archive.org/download/StanleyToolGuide1952 and this collection of wallcharts, published in the UK:
https://archive.org/download/StanleyUKEducationalCharts
You'll see that the pictures are the same, except for the company name and location.
However, it would make sense for the ITCL to include your version as well - it would make it clear that the same material was also published in booklet form.
Mark is keen to receive contributions of all sorts - he's had several from me, where he has been very helpful.
You could drop him an email on
