The Deltic locomotives usually sounded D# (or E Flat - frequency 311Hz) and G# (or A Flat - frequency 415Hz) notes separately - the Trent Instruments KS 1 is ok for the D#, but they do not seem to have a G# available in any of their horn series.
If you could get hold of a K5LA Nathan locomotive horn in the USA the number 1 and 3A bells would suit your purpose!
