Some detailed views of the 6281:

As can be seen, 10-degree extra-wides,
unibody (probably has a prism carriage), solid focuser design.
Likely to have a nice view but to need cleaning inside
and a bit of re-greasing.
Old 7x50s go quite cheap, but perform very well, to this very day(new)
for the price. That's the nature of the beast. I have compulsively
bought and cleaned .... too many ;-) The contrast and eye relief are
a joy, but that's after a good cleaning. The grease on the guide tubes,
which acts as a dust trap, dries out.
Ones that look like they sat in the back of the closet under stuff
(paint and case are fresh) can be good-to-go, though.
A warning about all the 'metallic-shiny objective' new binocs
(sharper image, vivitar, black series, minolta etc)...they are a horror.
They are extremely dim dark green looking through, and flimsy.
No achromats inside. Why put them in, when only green comes through?
