Any suggestions for a font that is similar to the one in the image below?
If you have a look at the real thing...
You can see that all the terminals are straight and not rounded, and the R in particular has a soft angle for its sloping leg. That and the overall proportions indicate that the font is Gill Sans Bold, which was popular for this sort of thing in the 1950s.
This is obviously hand-made, but Granby is quite similar in looking like a slightly more condensed version of Gill Sans with a straight leg.
