As drafts go, it's a real winner. When I'm taking a break from working TM 9-1270 I do some pages of FM 23-41 which has differing dimensions and print density for nearly every one of the pages.

If you update that pdf I'd be interested in seeing it. The only other Remington I have is a 521T and if you have a user or service manual for that I'd be all over it!
