Combination Ford Wrench

[petercl10]

Wondering if you guys can help out.  Found a tool at a sale and picked it up.  Thought it was cool, but I'm a history type guy. 

It is a combination wrench.  15/16 open end and the box end is 6 point I think 5/8.  There is Ford on one side and a circle M and the number 39 on the other.  I have seen ones that say 40 but the Ford looks different. 

Any help would be great.  Just looking to learn what it is.

That is a Ford head bolt and spark plug wrench made by Moore Drop Forging.

Probably one of the most common Ford wrenches out there. I must have 6 or 7 of them. There is more Ford wrenches than there is old Ford cars.

Thanks a ton guys.  Any idea on what it came with or when?  I looked for photos but only saw ones that had the "ford" in a different location and a number 40 instead of 39. 

Thanks again.

Some are specific to Model T and some to Model A. Some are likely tractor wrenches. Need a Ford wrench guy to answer.

the wrench should have a part number, if the prefix is T or TT it's for a model T, A or AA for a model A,
the there is the numbering, 48 is 1936, 78 is 1937, those I'm pretty sure of cause I have panel trucks from those years,
if there is no part number it is most likely aftermarket! lots of them out there too!
