Mine was the same one in 1969. In the early 70s I was in the military. When I got out I let it get to shoulder length. Right now it’s halfway over my ears. My wife can’t stand it. I figure I’ve saved about $45 in the past 6 weeks.
FWIW, three years ago I bought a trimmer set for $55 CDN. Haven’t been to the barber since. At $22/haircut every 3 months, I am now WELL ahead of the game.
You can buy a buzz cutter for less than that and keep that regulation look!
