No Winkler doesn't have a web site.  They even sell thier catalogs for around
$20 each.  The closest thing you can get is to check out my website at
http://www.vanagain.com as I am a distributor of thier stuff.  If there is
something that you are seriously interested in I can fax you a picture of it
from my catalog that I have.
