Vintage Lawson Perspective Charts Set of 8 Rare Drafting Tool Poster (2 Manuals)

Description

Enlarged 8 Page "Revised" Manual
New Copies of Original Manual
Charts in Good Condition
I originally bought the edition of folded charts which proved worthless, even after costly laminating. I then bought two sets of the top quality unfolded charts. One set came in the original mailing tube as the "Revised Metric and Imperial" version. While the manual seemed to be an improvement, I was unable to see the white dots in the vertical line mentioned in the last paragraph of "Procedure for Charts 1 to 4". If you read this section, you'll see the use of those dots, depending on value, is minimal. (Image #3) So, I think the charts themselves are the original chart design.
The charts of the two sets I am selling are identical and in good condition. Effort has been taken to enlarge the 8 page "Revised Edition Manual" to make it easier to use. I also noticed that the original smaller manual has its plus points and therefore duplicated it also.
The charts being offered come with the enlarged and reprinted directions, not the original smaller. (I only have one each and two chart packages to sell.) Each offer comes with the bookcase on tracing paper for overlaying on the charts.
I have two sets to sell and the two packages will have the same contents.
