Hot Lucas mag that will fit many of the earlier British marques where the dynamo is not incorporated with the magneto.  Shipping to the lower 48 states $20.00 (it's heavy). Tested via bench with drill - nice spark.   East of Rockies probably cheaper - will refund if appropriate.  Numbers on the tag I can read are:  4E5109    741  AC20,  also can see MO1(?) *(?)  4 .. Mag rotates clockwise when viewing from the left (point) side.
