This is the very long-lived L-86 "Auto-Lumi," a nice little selenium job that was very light and easy to use. The case is plastic and rather dull, and it's only got one scale.
Sekonic made this for fifteen years; a long run for a meter. It was finally retired in favor of the L-188, which is almost identical but uses CdS.
