I just had to have this old photograph when I came across it. An RM Riley photo-bombing a family photo in Switzerland. What a find!
And it’s got a roof rack like the one in San Remo (Riley at the Casino)!
My guess is it’s a 1.5 litre RME rather than a 2.5 RMF, which had a slightly longer bonnet, but it’s a way to go for the smaller engined car. Maybe someone in the Riley RM Club knows something about HWS865. Maybe it’s survived and someone still owns it!
The other car looks like a Ford Taunus 17M, which were produced from 1957 to 1960.
