Still need help with Harrison bros & houson knife set

[jeanette25]

can anybody identify this knife set?
The lid reads as follows:
a crown over the word alpha
Harrison bros & Houson
Silversmiths and Cutlers
Sheffield England
The handles I think are stag horn with silver end caps.
The case is I think leather covered wood.
I would like to find out how much this set is worth.
