Here’s a photo of a metal plaque attached to an unknown machine made by W. G. Goetz & Sons Ltd. under licence from the Buffalo Forge Company, USA.
The ‘Ltd’ on the plaque indicates a date after April 1939, when W. G. Goetz & Sons Pty. Ltd. became a public company, dropping the ‘Pty.’ from its name.
If you know what it might have been attached to or have more info, please leave a comment!
