I recently picked up a pair of Trinovid 10x42 BA. Very heavily used. Both eyecups were broken and taped in place, and the focus wheel was a bit stiff at near and far focus. But the optics were exquisite, and I've always loved this model.
As I had read on here about Leica's recent shift towards a more generous warranty policy toward binoculars bought second hand, I was curious to see if there was any chance this could be fixed under warranty. Unfortunately, the serial number turned out to be 1009xxx, which dates it to 1990 and 32 years of age, making it just a little bit too old. But the price was extremely good (€240), so I am definitely happy to spend a bit on fixing them. They were actually totally usable, but I'm guessing that this is as good time as any to get them fixed and ready for 30 more years of heavy use.
After a brief exchange of emails with Leica, the binoculars are now on their way to Portugal. I'm really curious to see what they will suggest, and I'll report back here what the outcome will be.
Sadly I forgot to take "before photos", so this is all I have:
