Find font in my High School logo (Ottawa Technical High School)

[stretchy]

My high school closed back in the 90's, so there is no help there. I am looking to find out what font they used for our school logo. I am not able to find it anywhere. The first attachment is the actual school logo. The second attachment is the individual letters copied from the logo to put in a line, hopefully for better reading. The "C", "E", "H", "O" and the "S" are seem very specific. I have found similar, but not the same font online.
