Interesting. The style was immediately recognisable as that which appears in 'Historic Carriage Drawings in 4mm Scale, vol 1 LMS and LNER' by David Jenkinson and Nick Campling. A quick look in the book confirms the match to diagram 1709, with the handwritten notes in blue/green ink now rendered word for word in draughtsman's print. Looks like you have been loaned some of the material used in the preparation of this (most useful) book.
Dr Jenkinson is one of my heroes too. It was he who made me realise there was 'more to it than the trains'; and fired my interest in the historical study of railways.
