I have set of 15x Swaros. They are about ten years old, used three or four times a year. I have the case for them but not the box. I sent them in a couple years ago for a check up, they came back with a clean bill of health. PM if your interested.
I have Leica 15x56 Geovid HD-R, Y (NIB - asking $2450). These have the built in rangefinder...similar to the Swaro model these can legit range out to 1400+ yards. Brand new with all papers including warranty card. I bought for a sheep hunt and was talked out of taking by my guide as tight canyon terrain did not need such magnification...and he had similar pair plus spotter.
