USHIN-SHOWA WEST916.SLA, Lost key, Unlocking the entrance door

"Lost key, Unlocking the entrance door"

It appeared that the apartment was not in his own name, but in his father's name, so the police were present.

Judging from the shape of the handle, it doesn't seem to be a MIWA, but the cylinder collar spins idly, so it's an LA type cylinder. I later found out that the handle shape is clearly different from those made by MIWA and GOAL in that the "R" bending of the L-shaped elbow part is smaller. MIWA and GOAL products are processed into a large "R" to improve synthesis.

The work was completed with normal thumbturn unlocking. After unlocking it, I checked the configuration and found that USHIN-SHOWA SLA was engraved on the front. The cylinder was "WEST 916-LA".
