NOTE:
JOHN BERTRAM & Sons, Ontario, built larger, heavy-duty and precise
machine tools until the 1960's.
Parts are still available. Many major American machine
tool names of the mid-twentieth
century were also built in Canada, and in many Bertram
versions, they were IMPROVED
on the original design. Examples are Niles-Bertram,
Cincinnati-Bertram & Acme-Bertram
etc. In MOST CASES, the BERTRAM version
was better built, often because
the improvements were not yet incorporated into the
original American design.
