The plastic and the key are both stamped zing, and it looks like the pictures, minus the sticker around the body. I don’t have a reason to doubt the authenticity of the cheap, recycled, Chinese lock 😂
Though I’m not sure it’s Abus internals. I have a 700 series zing coming in today to compare. That’s like the ones you bought, I believe.
This one was actually quite difficult, for what it is. Took me far longer than it should have to figure it out, which is good.
