Had the conways valve on my A and B. For many years never a promblem. With it I know of only one bike that it would suck open on but that bike had a worn out pump on the suck side
Also it's brass and looks Like it belongs on a A
Nice bit of kit better than a tap you could forget . But I always check my oil return on the first start of the day
