Its hard to see from the single photo, but I agree that this antenna does not appear to be wired in as a loop. I think I see only 1 wire on the back board.
However I have modified 2 Philcos and 1 Stromberg that originally had antenna transformers (and external antennas) and replaced them with home made internal loops. In each case reception was greatly improved. At my location I have large amounts of broadband noise, rendering wire antennas almost useless especially at night. I found radios with loops to be quite a lot quieter. It takes a bit of care to adjust a loops inductance to track properly, but once done it works very well across the entire band.
