Two (2) vintage sets of Jiggers Complete Soldering Kits manufactured by Samson United Corporation in Rochester, New York.

These were used to get a perfect soldered splice in 20 seconds with no torch - no iron - no solder pot.  

Each box measures 1-3/4" x 1-3/4" x 1/2" and contains six (6) jiggers.  Instructions on how to use them are printed on the boxes.

Great vintage collectibles or repurpose them for other craft projects.
