So what did I find in the attic of the CRC booking office? A large box with cast iron GWR letters ! Here they are in my garage:

Original cast iron GWR letters

Unfortunately, the letters are all different sizes 9 ins, 7ins, 5 ins, 4 ins, 3.7 ins and 2.8 ins. Any ideas what we could spell?

I almost have 'RACE COURSE' in the correct 9ins height. What we still need is a 'U' and an 'S', and maybe a better 'R'. Furthermore, we need 'CHELTENHAM' in 12ins letters. Also 'BROADWAY'.... anyone got any ideas where we can get such cast iron GWR letters? We also need lots of the smaller letters to do the Broadway 'V' boards.
