I recently inherited a nice pair of Swift Osprey Mark II 7.5 x 42 binoculars and I have a few questions:
- What's the difference between the Mark II and the original Osprey?
- What was the original retail price of the Mark II (either in the USA or UK)?
- The diopter ring is somewhat loose and turns around freely. It still works (with some fiddling) but I wonder if it can be repaired by a novice. (I couldn't figure out how to remove the ring, so it's probably best if I just leave well enough alone.)
