Hello Mike and Richard, I've got to put my hands up to this one. It was me who posted it before and who mailed it to Mike.
I 'm sure that it is Morris Commercial as the forum suggested but I'm just a bit niggled that I can't find a picture and confirmation anywhere of exactly which model.
I have mailed Mortons Publications who now hold the photo archives from "Motor Cycle" where the original appeared in the hope that I can obtain a better print because I think that I can see the MC badge on the rad. It's a nice picture anyway and I will be happy counting rivets on the 16H whatever
Rich.
