Good question. By part number prefix, 070- and 071 are manuals. 069- are manual files that are sources but supposedly would result in an 070 or 071 manual. 077 are electronic manuals only with no physical print manual. 020- are manual accessories so I don't think that matters. I suspect the RPR for , -070, -071 and 077- would give you all the information. What you would want is a a reverse lookup. Unfortunately OCRing a RPR doesn't result in high accuracy. I don't know how large those categories are. I'll look at the museum next week. Next on my list is to scan the 366- RPR category which is pretty large.
