SHOWA CL50.WEST916, Unlocking the entrance door by not carrying the key

"I left my keys at my parents' house when I returned home."

This time of year seems to be good. It seems that she arrived late at night, but she stayed overnight at a friend's house and then requested the next day. That's a wise choice.

Now, when we check the target lock on-site, the cylinder collar rotates freely. The handle seems to be MIWA type. However, when I checked after unlocking it, it was SHOWA CL50. When I looked closely at the J-shaped handle, it looked similar to MIWA, but the handle part was not square but rounded. I remembered that it was also used as a type of SHOWA SLA before. This is from 20 years ago, but since I come across it so rarely, I sometimes make mistakes in my judgment.
