I felt passionate about the Surveying industry and wanted to preserve a bit of history, in this electronics day and age, for a generation to come.
Just about all of my collection is over 100 years old and I now only collect instruments pre 1900.
I have done extensive research into the dating of instruments but there are some instruments that I cannot find any information on, but I have had quite a few instances where I could not find information on the web and after looking through various old text books was able to accurately date an instrument from manufacturer’s advertisements in the front and back of the text books - a pretty exciting moment when I come up with another piece of the dating puzzle. Other exciting moments occurred when I was able to trace an owners name on an instrument or wooden case and track down information on that owner through ancestry.com.
One of the purposes for setting up this web site is to enable any visitors to provide comments or correct any information on any of the articles listed or even to try to find out more about their own instruments in their collection.
There were no calculators nor computers available to our office in 1969 and all computations were carried out using log tables. All drafting was done with bow pens and nibs on linen and heavy weight fieldnote paper and field work was carried out using a steel band and micrometer theodolite. The unit of band used for measuring depended on the unit that a Title was issued in eg if the title was in Acres Roods and Perches ( usually a rural title) then a chain band was used and when the title was in feet and inches a band marked in feet and inches was used ( usually urban areas.) Conversion to the metric system in Australia came a few years later in about 1974.
There have been many sources of information that I have accessed to date my collection and I have tried to keep the information provided as factual and not plagiarize any works without reference or acknowledgement of the original source.
I appreciate feed back and would only be too happy to list reference to other websites if requested.
Any of the instruments with tripods are available for hire for movie props, or the like, and can be supplied for the era between about 1840 to 1920. Contact me via the Contact/ Comment button.
