I have a 1930 Fordor with Engine # RF7428. Does anyone know what the RF in the serial number means?
 
Look closely to see if the number rising has been ground down a bit. This could be a local rebuild shop's number.
 
I thought "RF" meant Real Ford", not one of these plastic jobs you buy today.
 
Thanks folks for the input. Now I believe I have a legitamit block numbering. I have found the diamond as referenced in link from BOB C.
 
It's possible the RF might be AF. I've mistaken a rusty stamped A for R before on an oil seal number. Could happen.
