I have RARE LAGANKE Racing , K&K Racing Armature Rewind Wire Spools .
LAGANKE Racing , East Cleveland, Ohio. Has green wire and is marked on the bottom 39 .
K&K Racing Products , Huntingburg , Ind. Copper colored wire , I don't know the gauge .
The bagged and loose spool look like they are a Reddish color.
The bagged one says " 38 " I suspect the gauge size.
