This chart, courtesy of TractorData (http://www.tractordata.com/farm-tractors/000/2/9/290-farmall-h.html), shows the 1st serial number for each year.
(i.e. if your serial number is 12345, then the tractor would be a 1940.

Based on the chart Roy provided your H is a 49 model. The wide front end was an option and was popular in some areas. It could have been delivered with the wide front axle or changed later.
