Originally posted by Benz3ne Cokin 58mm (I think) adapter and a couple of filters. Not sure what the clear one is about just yet so I'll do some digging. The 'blue' one could perhaps be an ND? Not sure, outside my knowledge-set!
Weston Master V light meter. Interested to try this out, probably won't keep but you never know!
The Cokin filters mostly look like NDs but maybe the blue-ish one is to correct tungsten lighting for daylight film.
I haven't seen another Weston meter for a long time, they were the bee's knees once and my father had one, but after he died mother gave it away to a friend (one who probably did not understand what it was for)
Then I got another among a lot similar to yours, but one day it suddenly stopped working, not that I dropped it or anything.
