Sorry about the pictures, hard to take pictures of yard sticks so I will explain. First picture top says Quality auto supply, Main St. Charleston, Arkansas with a phone number of 123. Bottom of first picture, Hanna Gray Company, Phone sunset 2-6088 55 South St, Fort Smith, Arkansas.
Second picture top on the other side, Thompson Products-use thompson valves, guides, springs, valve rotators and valve seat inserts
Back side of bottom yard stick, Sealed Power-individually engineered piston ring sets, the only ring with the full flow spring.
Last picture is the phone number of the top stick.
Oh yes, sticks to use to keep your valves in the proper order---
