Mystery Objects. What are these?

I bought these for use on a future project at the house. Can you guess what they are used for?

I’ll give you some clues:

  • These items were probably produced in the 40’s, 50’s and 60’s.
  • Very unlikely to find them in a modern house.
  • They would typically be used in twos or threes, i.e you may use two or three of the same numbered tacks together.

Winner receives a jar of our homemade DnA chili sauce. Local winners can pick it up, for others I will ship.

Winner to be announced next Friday.
