Mike, those are great pictures and a very nice pan. I grabbed an old picture of my 1314 with the cast handle and cropped it to be similar to your close 1314A picture, grabbed your picture and pasted them together so we could see them at the same time. Mine's on top, yours below.
I can't tell from you picture, are the numbers raised or incised? They are incised on mine. The serifs do seem different on the numeral 1.
And Steve, does the 1924 catalog talk mention the handle being one piece or two, or is it illustrated?
Tom
