My father passed away leaving his rather large collection. I have done some research via the internet. Wow it's fascinating. I need help identifying several pieces and determine a reasonable value. My 2nd piece is a raised 7 on top of the handle and a gate mark on the bottom of the pan. The raised # indicates to me pre Lodge (Blacklock). I'm not sure since there is no visible raised letter on the bottom of the pan.Thanks for your help.
