4.30. Part of an Unknown Building
This last-minute addition (29 June 2021) grew out of the process of making the tunnel access panel labeled B, above, with the building at #30. Work began on 5 July 2021; the origin of the structure is a kit—American Model Builders' A.C. Brown Manufacturing Co. #615—originally slated to become a printing company on the Mountain Vista Railroad in an early draft.
