Two pictures that might be of interest to your readers: I have just finished restoring it in the last week of August, 2000. It is a 7 HP Magnet built by the Petrie Manufacturing Company Ltd., Hamilton, Ontario.
The bore and stroke is 6?' x 8.' The serial number is #71055. I do not know the year built. No records from the company have surfaced yet.
