The objectives were a bit hard to unscrew but it worked out fine. The construction looks beautifully simple but it´s a lot of precision in the details and I got a feeling why these instruments were so expensive in their days.
The build quality is fantastic and both prisms sit absolutely tight in their housing without any play, but are easy to take out after the strong metal clamps have been removed. I´m not a technician, but following Simon Spiers´ fine video (thank you so much!) about cleaning porros and fetching the tools, paper towel, acetone, window cleaner and rubber gloves I had some fun. It seems the plastic seal on the prism plates has turned into a waxy substance and fogged up parts of the prism. I gave my sample a thorough cleaning, both from top and bottom, both prisms each side, and the rear lens of the objectives. Some of these guys also clearly prefer the Binuxit to the Zeiss West. My Binuxit seems to be a rather late one, probably from the second half of the 1950s, Holger Merlitz states the Binuxit was built from 1927 till 1962 () and there is a very nice flickr page with comments of passionate users. I plan to have my sample serviced, it´s worth it because on a sunny day it is a pure pleasure and wow, this is just a decollimated sample.
Combine this with a 150m field of view and ease of view and you will just fall into the image like with few other binos. Nevertheless the sharpness is spectacular. The Zeiss design is many decades newer - but much inferior in usability and optical quality (I had 3 Zeiss for comparison.)! The ocular lenses of the Binuxit have about 4 times the surface of the Zeiss West. When comparing the Binuxit to a clean Zeiss West 8x30 (No.5xx xxx, non B) I was shocked how sharp, bright and neutral the Binuxit looked in comparison. Definitely one of the greatest binoculars ever! Leica could build this with modern glass and coatings and have a real stunner in their portfolio probably even beating my beloved Habicht 8x30. This is the very best vintage bino I have used.
