This SATO Hand Key is a rare find in this condition. They were a well made Japanese key with ball bearings giving it a nice, smooth feel. Plated hardware, Bakelite base and pivot block. The base measures 5 3/8" x 3 1/4" - Height approximately 2 3/4" - Some light pitting on rear terminals. No visible cracking. Looks very similar to the Dentsu Seiki KK - but has a Navy knob - which appears original. As a display piece in my collection since the 1990s, it saw little use. Never could find much information for this SATO but I've been told these were produced late 1950s thru early 70s (??) A nice addition for anyone interested in vintage Japanese keys - Collect, Display -or- Play. Your Choice. Will be well packed - Shipped via USPS Priority / Insured. ( CONUS, HI and AK ) Price: $ 90.00 PayPal preferred, USPS MO accepted. Contact via my QRZ email - Tnx !!
