Hi Edmund,
The link for me is good,the site is real,good and regular for knots;
maybe your antivirus is set too"alert";
currently I'm on a Linux O.S.,and I no have a resident antivirus installed,
I hope the site will no be a victim of something.
I must say however that in the text above the pictures of link posted by me,
it contained an inaccuracy in regard of Ashley Bend:
what is written should be reported for Hunter's Bend.
the second bend posted by you appears like a sort of variation of Zeppelin Bend.
As the author points out, the only knot that does not difference,
about how the two loops are intersected,is the Butterfly Bend,
because the two loops are symmetrical in form and position,
and in this case if you interchange the way to intersect the two
initial loops,the result is always a Butterfly,
but a mirror version of the other
About the Butterfly, I had to be more accurate:
the symmetry must being understood in the sense of the vertical axis between the two
interlocked loops in first step picture of Butterfly in the same page:
http://daveroot.co.cc/Knots/Knots_Bends.htm#AlpineButterflyBendthis because,for example,in the Ashley Bend too
"the two loops are symmetrical in form and position", but in this case
the axis of symmetry is diagonal between the two
interlocked initial loops:
http://daveroot.co.cc/Knots/Knots_Bends.htm#AshleysBendin this case,if you interchange the way to intersect the two
initial loops,the result is not a mirror version of Ashley,
but another knot(ABOK #1408),the same of Captain's bend in your document.
Both these knots,after dressing and setting,
results to be very symmetrical in front/rear view sense.
Now,your Rosenwind Bend (which from now on, as rightly pointed out by X1,
we are obliged to call Mark's Bend or Rosendahl Variant),
is closely related to 1408/Captain 's rather than with the Zeppelin
(that night I wanted to respond to you briefly without tying the knot, I did not have time!);
Moreover, even agent_smith (despite having called Rosendahl Variant),
in the text above the pictures of the first link posted by X1, says:
"This variation can also be tied from #1408 as a starting base - and then untying one side and then re-threading so that the tail goes in the opposite direction to obtain the crucifix / Rosendahl form.".
If the Mark's Bend don't have this front/rear symmetry is because
the two initial loops are symmetric in position(diagonal axis),
but not in form.
EDIT:A bend more closely related to the Zeppelin is the
" falsely tied Hunter s bend"presented here:

are interlocked only by the tails,and this is the genuine reversed version
of ABOK #1425(sorry,yesterday I forgot to write).
OK,stay well!
