Found it! By accident of course, rooting through piles of crap looking for nothing in particular except for maybe a mag that needed another read. I've referred to this article in a few other threads in the past. I can scan it tomorrow, the scanner is on the desk in our bedroom now and the missus is sleeping. But this is legible enough I hope.
9x9 APC on an OS .46 VF-DF, no cowl, 207mph is noted here as a radar track. It took a cowled Nelson FAI .40 for CP to break the magic number by two. I've nibbled on it with a cowled OPS .65 (now a fresh .67). Beats me.. whaddya all think?
