How does this "Light meter stripe" work?

[IloveTLRs]

While looking for Minox bits & pieces on the bay, I came across this Minox Riga light meter stripe .. http://www.ebay.ch/itm/Minox-Riga-B...811930?hash=item2a6139ea5a:g:zUoAAOSwT5tWQhgZ

Does anyone know how it works? Do you look through the clear strip below the pictograms?
I'm guessing the numbers at the bottom correspond to film speed? (Minopan 25, Tri-X 200 etc.)

I'm puzzled. There are indeed various visual extinction meters.

But your stripe contains a scale with "wattages" of lamps and a distance scale.

(No, it is not about film speed, but likely means 15-200W plus Nitraphot lamp (overrated photolamp).)

You can also make your own parallax distance finder:

Hmm, I had guessed the film speeds would fit down there. I now see the Submin website entry on it.

I was wondering if it would be possible to recreate this in Adobe Illustrator, just for fun.

Am still puzzled:
First we are shown a strip, stated to be the complete meter.
Then we are shown an apparatus somehow incorporating this strip.

There is an explanation here, as to how it works: http://www.submin.com/8x11/collection/minox/accessories/exposure_table.htm

But then the ebay offer is erroneous: "LightMeter - 100% working condition"

Maybe the seller means "100% working, on the condition that you have the other part.
