Salopian, I have all of my research material on Annie's stock dimensions in front of me, including the PCGA letters on all of the attributed Annie guns listed in The Parker Story, as well as the Lancaster dimensions. If you will give me the specifications of the gun you own, I will give you my opinion of the Annie connection of your gun. I assume your gun was made after the Lancaster measurements were taken. What brand is your gun? The circumference of the grip is part of the measurements also.
