Lot of 22 Vintage Engineering Drafting Templates - Ellipse, Torx, Triangles, Etc

Description

I am selling a lot of 22 Vintage Engineering Drafting Templates including Ellipses, Torx, Triangles, Curves, etc.
They are in used condition. Dating back to the 1970's and 1980's.
My friend's father was a mechanical engineer and inventor in the 1970's and 1980's and these all belonged to him.
These were his "tools of the trade".
The manufacturer's names on these templates include:
CamCar
Dietzgen
Keuffel & Esser Co (K+E)
Kaylock
Tru-Guide
Lietz
Charvoz-Roos Corp (that's the one that is broken).
Rapid Design
Some of the triangles have no manufacturer name on them.
One of the ellipse templates has a crack in it. The photo has a note showing where the crack is.
If you need any more info or more photos, please let me know!
