Some IBM Core Memory Artifact Help if possible

Hi Can anyone provide: 1) The dimensions of the memory plane from the Type 738 Memory used in the IBM 704 and other computers of its generation. There is an undimensioned photo in Pugh's "Memories That Shaped An Industry" C 1984 (p.158) that makes a 4 KiB plane look to be about 14 in by 7 in. A high quality photo would be appreciated. I can send anyone a scan if they care. 2) A photo and dimensions of the M4I memory plane (that's M4eye not M4one) that was used in the System 360 M65 and M70. The Computer History Museum has an artifact identified as a, Magnetic Core Plane, IBM /360 Model 65, http://www.computerhistory.org/collections/accession/102627815, but it looks too small and too crude to be for those machines. I could be wrong so I would appreciate someone who could verify the artifact or alternatively the correct photo and dimensions. Pugh is unclear but he does imply a much larger frame. This is for a web exhibit I am preparing for the Computer History Museum Any help would be appreciated. Thanks Tom
