engine tag
I was dismantling my 53 ford flathead v8 today and on the front of the engine is a brass tag that says - M&M Auto Parts Co. / Genuine Remanufactured / Detroit ID or IO not sure , Michigan , Then below that it says - Bore 030 / Main 010 / Rod 020 / Job 24 , I tried to google it but I believe this business is long gone , Just thought it was kind of neat , I took a picture of it but but have no idea how to upload.

Re: engine tag
It is Detroit 10, Michigan. The 10 is the area of the city before they had zip codes. I think the number was called a zone number if I remember correctly.
Probably the area which now has the zip code 48210, just East of Dearborn. |

Re: engine tag
Dates When Postal Zones and Zip Codes Started
POSTAL ZONES - You may have noticed that many addresses during the period between 1943 and 1963 had a one or two digit number following the city name. These numbers were postal zones. It may surprise you to learn that postal zones were instituted in 1943 during WWII. They were necessary because many postal clerks had gone into the service and the new inexperienced postal clerks were having trouble sorting the mail. The zone system was put in place to make things easier. ZIP CODES - By 1963, most of first-class mail in the United States was generated by a small number of large-volume mailers, so The Post Office Department devised a plan to speed handling and delivery of letter mail. By this time most businesses had automated mailing systems that could easily handle the 5 digits that would allow mailings to bypass as many as six mail-handling steps. Zip codes went into effect on July 1, 1963. ZIP stood for Zone Improvement Plan.

Re: engine tag
Postal Zones as in Elvis' Return to Sender, "no such number, no such zone"
