Ooops ... this is where I blush and appologize for not correctly 
remembering the sequence of issues I encountered. Going back to capture 
examples, I found that the content now ungzips correctly.  Digging 
further, it turns out that I had this problem before I discovered that
transfer encoding chunked was being incorrectly removed. 
Since I had already added built in gunzip in the extract tool, I had not 
gone back to try the gunzip.

Sorry about crying wolf without double checking my results.
