Yesterday, before reading this, I made up a replacement ersatz B114 for my Ekco Princess and noticed that it was the width dimension that seemed to vary between the two makes used, one type were more bulbous, for lack of a better word. I want to make up a proper battery box for this rather than just taping them all together but I starting to wonder if it is viable. I am going to feel a bit of a charlie wandering quids-r-us or wherever with a vernier!
