I just bought what is supposed to be an old style 88 standard.  It appears to be anatomically correct but the serial number tag is missing.  Is there another way to identify this tractor?  On the left side of the engine are the numbers 190120B K100B.  On the right side of the engine are the numbers 12 12 7 stamped on an angle upside down.  I have no doubt it is a standaard 88 but would like to confirm it is truly an old style and not a fleetline with streamline sheet metal.
