Hi Guys, as this question comes up very often, I thought it would be useful to place a pinned thread on the subject?
The key to determining an original from a fake, like so many other German items, is the reverse.
Here is the edge detail of an original. Note the pattern of the weave and how it forms a series of small almost even sized white "dots" right near the edge of the cuff title? This is only seen on originals.
The chequered black and white weave which forms the back of the title is known to collectors as "salt and pepper" weave.
