Thankyou to those who had suggestions today.  It gave me a starting 
place to look for illustrations, etc.

Cross-peen it's not, according to Webster's 1910 edition.  Webster 
says the peen of one of those runs crosswise to the handle.  This one 
is parallel with the axis of the handle.

Esther's blacksmithing lead might be close.  The 1902 Sears reprint 
shows a horseshoer's turning hammer of the same weight and relatively 
light handle - but again, it's 90 degrees off.

The fact that this one shows no sign of ever bashing into iron doesn't 
mean much.  We don't know if the man ever used it for it's intended 
purpose.  ( And my auto body tools aren't bashed up either.)

Probably more interesting - Webster's 1910 includes cross-peen.  
American Heritage Dictionary of 1992 comes no closer than 
"cross-dress".

Such is our American heritage.
