I was cleaning my shop at the cemetery where I work and tucked under a shelf on a ledge I found this ruler. No one working at the cemetery remembers ever having seen it before. It may have been there for 20 years or even 50 years. I found an oil change sticker from 1974 on the ledge near the ruler.
Lufkin No. 7165 - its a 10 foot sliding rule of two 5 foot sections. It has some wear and tear but is still functional. Archive.org has a 1935 catalog listing the ruler - a quantity of 12 could be purchased (wholesale?) for $30 ($2.50 each). In today's dollars a dozen would cost about $650 (or $54 each).

Hello, Al. Nice find! I have seen similar rulers, one offered by a metal kitchen cabinet company. Could also be used for squaring boxes , we just call them measuring sticks!! Great for inside measurements!! I will check the catalogs!!
Thanks to Internet Archives and Rose Tools for the photo!!
Used to use long extension rule all the time for checking overhead clearances in the plant when laying out conveyor paths.
