Found by Hayden Callahan in Cobourg, Ontario, Canada.
Note – I am not in possession of this example.
The manufacturer is unknown but what can be seen of the stamp would suggest it was manufactured in Scotland.
Below – The top line may be missing 1 or 2 letters at the end. The stamp appears to read ‘RYPE?’ This would likely be a trademark as opposed to a company name.
The bottom line appears to say ‘SCOTLAND’.
