I have spent a few minutes searching online for the manual with no good results yet. Anyone have a link for a .pdf of the manual? Any good books published about mags?

Ooh Tim! I'm grabbing these pics to supplement the manual I have from oldcroak! Thank you!
Danny, grab these pics from Tim.
Compare the pics to this manual at oldcroak. I certainly believe they are two very different manuals! Cool!

Fantastic pics and always wanting more A-B info as these mags are in the OT world too. Old tractor world. Shhh.
Just barely scratching the surface into the U-4 mags and what's correct for an OT engine I have here! Oop.
Have a U-4 (one more on the way), a couple ZR-4's here also but the DU series is an interesting mag to me!
Good mags.
Thanks for starting this Danny!

Tim, Danny,
I hope you don't mind but I've taken the images, cleaned/straightened them as best as possible, and created a PDF manual.
The result is attached here, I've had to downsample it 'cos I couldn't upload a 5.7MB file, but it's ok I guess.
Tim, perhaps you could check if I've got the pages in order? I have a feeling there may be a couple missing, but I'm not really sure?

for some reason I just took a liking to these. Don't know why, they are just cool!! We need some reprints of those books!
Luke,
I haven't had a chance to compare your compiled file, but thanks for the effort so far.
