I've finally dug out the CI&L specific F2/F3 Operator's Manual, dated June 1, 1947, with unit numbers from their initial order of Freight F3's. Interestingly, it already has the BL2 insert incorporated in blue paper, which I hadn't noticed before. Here's a few photos of the manual. I have, and have seen, other F3 operator manuals, but none that have the Monon specific pages in it.
