Hi Don:

thanks for being so understanding of an old TFer like me

It will be interesting to hear from Ken's contact in Australia I sure hope that he will stop by the site with his educated slant on this topic.

One has to be careful of articles that appear in magazines they sometimes are not backed up by accurate research.

When I had access to the UCV research library I could wander through publications like the canadian patent records which I did many times over the years to prove or disprove at times issues that were before me.

We also had issues of 1860 hardware catalogues that were filled with items that could be purchased by local stores for sale abroad and locally.

Circular saws in their primitive forms were there as well as cloth tape measures that could be rolled up much as our 50 foot tapes are today.
