I think I have resolved the issue of who the New Haven Edge Tool 
Company was, and just purely by luck and a 100 year old accident.

Today, an auction on eBay ended for a gouge with a double stamp.  The 
original stamp was "Jennings and Griffin".  On top of that stamp is 
"Haven Edge Tool Co.".  I have relocated the photos of this chisel at 
the link below.

I tried to snag it but was sniped.  Live by the sword, die by the sword.

This seems to clearly indicate that Jennings and Griffin were 
producing edge tools for Sargent under the New Haven Edge Tool 
Company name. This makes a lot of sense because Jennings and Griffin 
was a New Haven outfit (Yalesville, I think it is technically 
Wallingford) in operation while Sargent was marketing NHETCo.  By the 
1911 Sargent catalog, the NHETCo. name was dropped.  Although it is 
unclear exactly when this happened, it may have coincided with the 
companies demise or it's being bought out/turned into a C.E.Jennings 
company, according to the DAT (no date specified).  Or Sargent may 
have bought the New Haven Jennings and Griffin works and the Jennings 
and Griffin production moved to the C.E. Jennings plant in Deep 
River.  Who knows.

  As I indicated earlier, there is no record that I can find of 
NHETCo. as a separate identity ever existing in New Haven 
Directories.  I also picked up a copy of the chisel page from the 
1894 Sargent catalog and it indicates that NHETCo. products carry the 
same warranty as any Sargent product.  Originally I assumed this 
meant that NHETCo. was just a Sargent brand name, but it appears this 
is not the case.

The DAT indicates that NHETCo. used the trademarks H. MACEY and 
CARPENTER, but I can't say where this comes from or how correct it 
is. The DAT also indicates that they were in operation in 1894, I'll 
bet this refers to the occurrence in the 1894 Sargent catalog.

So why did Jennings and Griffin sell chisels to Sargent under a brand 
name, as opposed to using their own?  The Sargent catalog contained 
many products from other manufacturers, why not Jennings and Griffin? 
Another mystery.  I guess the more we learn, the less we know.

The first mention I can find of NHETCo. being a Jennings product is 
in an OldTools post by Gary Allan May, #98674, October 2001.  Good 
call Gary, right on the money.
