I needed to map out something on paper today. It gave me a chance to use tools from a former life. These belonged to my grandfather. I was gifted them by my mum when i started uni as a mechanical engineer,as i never actually met him. They served him well as a designer of the prototype fast breeder reactor. Some years later they served me well on the decommisioning design team of the same site. I consider myself exceptional lucky to have placed them on the same drawing 50 odd years later although it wasnt in anger.
There is actually 2 set within the case, i assuke because at some point the other sets case was damaged.
I have another full set that was my fathers but they live in the instruments box so i didn't get them out today. I might take a few pics of that set at some point.
