No photometers? Or is the Weston a photometer?

[Don Joe]

Weston perfected the Selenium meter in the 1930s. I have some from that era that are still working fine. Megatron in the UK bought the rights and designs and makes a modified clone of the Master V (the last of the "great ones"), it sells for something like $300 or so. Do some web spelunking for "weston master light meter", there's lots of info available about them.
