Old-New Lodge Loaf Pans. 4LP vs. BW8LP
Lodge has a slightly different new cast iron loaf pan. The old model is 4LP, and the newer model is BW8LP.
The newer one has a bigger overall (outer) length due to the redesigned handles. This new one does not fit "squarely" in my toaster oven like the old one did. But it does fit if I put it in at an angle.
The newer one has sharper, less rounded, interior edges and corners.
