HI, I was very interested to see this post. A copy of Greenly's book has been in our family since 1916. It was given to my father (by his brother) while serving in the the Royal Navy.
This book more than anything else, set me on a career in the engineering profession, and is a prized possession.
Much the worse for wear , it is missing a few pages from which my father built the locomotive described.
Yes it is a very old , general look at the amateur's workshop ,but more than anyone Mr. Greenly showed what ws possible with simple tools.
As a professional he also designed several of the small gauge locomotives such those for the Ravensglass and Eskdale, and Romney Hythe and Dymchurch Railways.
