When I was a kid we had this lock that had a long tubular brass key with notches on four sides. It was about 2 inches long and had a hole at the tip, in the middle of the cylinder. I have never seen any other one like this in over 25 years but I miss this lock as it was pleasing to use: locking and unlocking felt very smooth. Do any of you could identify it only with this poor description? If any of you can, I would love to know if this is considered a good lock because as a kid I felt like this was the most secure lock in the world.
