For those who are interested in collecting mold number and year variations!

I have the following duplicates (mold year, year of manufacture, and mold number) available for trade --

1938 1947 19
1938 1947 14
1938 1951 27
1938 1951 4
1938 1952 5
1938 1952 6
1938 1952 7
1938 1952 9

I am interested in any mold numbers, or years that I do not have. The current list of what I have is here --> [http://myinsulators.com/ajg/Baby%20Signal%20Mold-Years.pdf]. This includes mold numbers and years of manufacture from Hemingray as well as other manufacturers, and shop numbers too!
