I splitted the Bulletin 310B Vol.1 in three parts + an appendix. I hadn't realized, that one page with the overall function diagramm is a folded double size sheet, that wasn't scanned correctly by the automated feeder mechanism. It is .pdf-page #5 of 310B_Mod33_TechM_Vol1_p2of3_Jun69.pdf Bulletin 310B Vol.2 is splitted in two parts.
