Vintage Mechanical Drafting Set Drawing Tool Compass 10 Pieces See Pictures

Description

Please see all pictures for best description and I would be happy to answer any questions the best I can. I will be listing several items from part of an estate, though I do not have much knowledge on vintage items I would be happy to answer any questions the best I can.
Most vintage items I list will be sold as found and not cleaned prior to shipping so they may need to be wiped down.
This set is complete as seen in the pictures, they do not show any corrosion but do show some discoloring and are not shiny could use a wipe down to make them look a little better. The snap on the case is bad it, the top flap is missing the snap but it does fold closed nice, it shows wear and tear from use but the tools look to be in good useable condition.
I do not see any markings as far as a brand, Please see pictures.
