I was able to pick up a Klein-Adler 2 for a decent price. It arrived in the mail today. The seller did an excellent job packing it. As you can see from the photos, the machine needs a little cleaning, and the slugs certainly need some loosening up.
Th case also came with the key, which is a rare find for me. According to the seller, it was manufactured in 1941. That seems a bit late to me. I can’t quite see the serial underneath the coil spring.
Now, there’s obviously something missing here. The spring coil is exposed. I’ll need to find something to protect it. Otherwise, the machine appears to be in good working order. The decals are not perfect, but they certainly are legible. I look forward to working on my first Adler.
