I have just completed the pdf kung-fu to publish the May 1943 version of the TM10-1562. That's the last parts manual before the SNLs were published.. It pertains to trucks from Mid 43 and EARLIER.
The PDFs will be locked down, and watermarked. But I will be selling un-watermarked and printable versions on e-bay on through this site.
It is fully searchable and the images are very, very good.
I don't have a link off the main page.. but the URL will be:
