The primary table starts to appear at LBA 2 through 34 (which is probably invalidated without its header). However, there's a backup GPT header and tables at LBA minus-34 to minus-1, from the last LBA which is still valid. I have no idea how the kernel or devicetree behave with such a disk, that lacks an MBR and GPT primary header, but contains other GPT structures.
