It is a replica of the DK-21 eyecup. As such, convinced the replacement part. Indistinguishable from the original. Fits wonderfully. But: 1. On the part sticking a label with bar code - you get it from and then one has hardly adhesive residue on the replacement part. 2. The supply comes from China. I've been waiting for exactly 4 weeks the replacement part.
Conclusion: If you do not hurry, here gets a good spare parts dirt cheap. All others must probably look elsewhere.
