This is most likely a special order key from a name line which is now part of Vibroplex. There is little indication that this key is under current production.
The key: A beautiful, Chrome Base single paddle keyer. All hardware chromed with bright red paddles which display no wear. Appears never used, heavily weighted for stability.
This key is unique as there are no physical contacts. The keying function is provided by LED and Photo cell interruptions. The key requires an external
power source ~9VDC. I have tested the key and it represents a quiet, truly smooth operation.
With little resources available to truly price this gorgeous key, it appears that this product line requested ~$400 for keys using the LED / Photo cell technology.
