I believe this to be one of the first of these 3A sets to come out of Binns Road once that factory was in production. It is dated September of 1914, very soon after tooling was moved over and they started the 1914 Christmas run. The Box had not yet been changed to accommodate the Sector plate of which there wasn't one in the 1913 3A Outfit! The Set is as I found it and I also have it's brother 2A Outfit from the same run
