Engine Serial Number Information

 

Please Note:  This info is incomplete and I am still trying to compile this list.  I am trying to gather information on decoding engine serial number identification prefixes (pre-1954) and suffixes (1954 - 1959) to add to this site.   If you have any info that can be added, please let me know.                                                                   

                                                                                                                         Thanks,  Keith Hardy
