Found some more print on this thing... indeed it is rare, and indeed, well made:
"Ankorex , extracts any stuck anchor
A very rare item. Works with any anchor
. If your anchor
is stuck, simply
send the orange messenger collar down the anchor rode
, it keys into
beautiful 316 stainless steel anchor shackle
(the Ankorex is load rated to
10,500 lbs). The shackle
then transfers the rode
pull from the shank to the
crown of the anchor. This backs the stuck anchor out with ease.
I needed the Ankorex after an appendectomy, when the doctor said I couldn't
lift heavy objects. This allowed me to sail for the summer. I have two of
them. You are bidding on buying one. The winning bidder will have his
choice of the one that is new and in the box, or the one that is set up and
ready to use, with cable, shackle
& chain. The used one is in excellent
condition and almost indistinguishable from the new one. This is a really
well made product. If you want both Ankorexes, I will accept ¾ of the
winning bid for the second Ankorex.
The shipping weight is 8 lbs. Rated for 10,500 lbs
The original price was $189."
Still seeking any user or manufacturer information on this anchor puller.
