Blenko Jug

I have a large Blenko two handled jug that I cannot id as to designer or year.  I believe it is either Nickerson or Shepherd but cannot locate a similar one looking at the catalog pages.  It is 15” high, 8” in diameter at the bottom and 9 1/4” in diameter from handle to handle.  It is in tangerine.  Any help you can provide will be appreciated.

Thank you,

DK
