I think the Eames vacuum brake cylinder/diaphragm on Mason bogie engines may actually have been
centered on the rear truck, rather than in the usual off-center position under the cab on the engineer's side. Compare with this photo from my collection of a standard gauge Mason bogie engine on the Long Island RR (LIRR No. 59, Mason C/N 702, built in 1883) fitted with Eames vacuum brakes. I've circled the brake diaphragm in red. It appears to be directly behind the firebox.
