Hello, I talked with my friend and she said that the pattern was from the 30's and if you have a quilt program call Block Base on your PC that this pattern is in there it is called Cog Wheel and the number that you would look it up on Block Base is 3455.
She did say that some of the fabrics are from the 30's and some from the 40's.
I hope this has helped you to find out more about this quilt.
Clara :)
