Up for sale is a NOS set of Vintage boatbuilders Caulking tools for packing or putting the cotton or Oakum into the seam between the wood planks. This is a complete set still in the original wood box. This set has 10 different caulking tools, and most are stamped with the Mfg. name KOVAR. The lid of the wood box has the name J.R.Kovar Co. , Anoka, Minn. printed on it. This may be a military set, as it has the number 41-1-430, 1 set , printed on it as well. I was told this was made in 1938. Very unique and one of a kind still in the original box. Good Luck offerding!
