Vintage Sekonic Seiko L-6 / L-VI Photography Light Meter with Leather Case.
Nice Sekonic Seiko L-0 (No.194190) Photography Light Meter with Leather Case.
I've tested meter and it responds well to low level lighting as well as high exposure - (I myself use a vintage GE light meter for my B/W film shooting with my SpeedGraphix - if you know what i mean :)
I plan to be selling more vintage camera gear on here - so feel free to save me as a seller.
