Really nice collection. Oof though, you wonder how many of the original copies are forgotten in attics or thrift stores. I'll have to keep my eyes open for a hard copy.
Those working drawings are nice. In the US, balloons would typically be interpreted as BOM callouts and flag notes would point to a list of text or an appendix. *Edit: Was looking through my Spitty drawings and balloons go to parts. Rev triangles are the same. Notes are typically written on the drawing instead. Doesn't matter to me, other than it's interesting to see different styles.
"In the UK, the model engine designer and builder LBSC used descriptions like 1/8" full to describe a running fit for a shaft, or 1/8" bare to indicate a tight fit for two mating parts for the same reason "
@deverett Do you know of a good source defining UK machining lingo like the class fit definitions you mentioned?
