I have a deckle lever cutter, similar to the one in the pictures above.

It has the name ISING ORIGINAL Bergneustadt Germany, it looks about the same size as the one in the pictures, I'm guessing late fifties to mid sixties, I picked it up at a photo flea market in Melbourne some years ago for a dollar or two.

It is an annoying size as the longest piece of paper it will take is 240mm, just a bit shorter than an 8x10" long side.

The cutter has seen an enormous amount of work, but still works quite well. I use it for family stuff on RC paper, works a treat.

Mick.
