From an email-

QuoteI was given your web cite by a collector who said you might be able to help me identify  a large double ended hexagon wrench that I picked up at an estate sale in New York.  I have attached pictures of the wrench.  It is 15" long, one end offset with hexagon ends 2 1/2" and 2".  It looks like it has "T 202" written on the flat side.  not sure about the T part but the 202 is clear.   It came from a three generation family of farmers in estate sale.  Thanks for any information you may give me.  Ethel Allman

 Number is suggestive of a Caterpillar wrench. They have several wrenchs with T-xxx part number,but haven't found a T-202. Size is also right for a Cat usage. Just a guess.

I am not sure it is T -202 or maybe T- 702.  Ends of wrench are 2 1/2" and 2".  I am really wanting to date it if possible and know the make.  Thanks
