Trade Directories - Stornoway

[Gadget]

Hi

Does anyone know of any online Trade Directories for Stornoway for roughly 1890 -1920, please?

I'm particularly looking for Donald McIver, General Merchant. All census and BMD information has him as this occupation but in his son's autobiography and marriage record (1911) he is down as a Tweed Manufacturer. I am trying to ascertain whether this was 'artistic license'

Regards
