Trying to recall the name of a vintage exposure table device

[Jimi]

I am racking my mind, trying to dredge up what this might be called - a lot of perhapses and ifs in here:

An exposure table, a proto-lightmeter so to speak, that was as far as I can remember made out of metal (brass?) and enamelled. It came in at least two or three language versions (french, german and possibly english, over a longer period of time). There was a lot of information crammed into it, as it often is with exposure tables (time of day, month, weather variables etc). Not sure if it had levers too. It was of french manufacture.

If I remember correctly, it also had a brand name that also was used as a denominator for the thing itself.
I think it might be dated somewhere late 19th century (1880-90).

Any clues might help me sleep at night again.

Are you thinking of the Posographe? It's wondeful.

More modern, there was the Jiffy-Calculator. I think it was originally for night exposures, but I have seen one that covers daytime as well.

Yeah - you got it!
I got to thinking yesterday that the name might have started with Posi-something and searched upside down and around, to no avail.
Wonderful, indeed!

Now I know what to look for. And can sleep at night too.

That will depend of the time you'll spend looking for one on eBay
