20th September 1921 Mackinlay & Birnie Bere barley invoice

The invoice indicates a new era at Glen Mhor with the inclusion of Glen Albyn in the letterhead, after its acquisition by Mackinlay & Birnie in 1920.

As we'll see from the next invoice, this template is the standard issue for Mackinlay & Birnie, allowing the office to type in the blanks and keep a record of any transactions, details and approvals. 

Apologies for the variable sound here, not sure what happened as it was recorded immediately after episode 12.
