wes williams Posted December 24, 2009 Share Posted December 24, 2009 As before, roughly 1897-1904. Here is the table again for recent members, based on dealer's labels, transitional markings, etc. 1..1500:1862 - 1864 1500..3200:1862 - 1867 3201..25200:1862 - 1878 25201..44700:1872 - 1878 44701..46999:1876 - 1878 47000:1878 47001..51000:1878 - 1881 51001..80600:1878 - 1887 80601..92000:1881 - 1887 92001..140500:1885 - 1896 140501..144400:1895 - 1897 144001..152600:1895 - 1918 152601..172000:1897 - 1918 172001..187400:1904 - 1918 187401..196800:1904 - 1927 196801..201100:1926 - 1933 Link to comment Share on other sites More sharing options...
hjcjones Posted December 29, 2009 Share Posted December 29, 2009 William Meredith's dating formula here on c.net places it around 1915-16. However all these methods are speculative and based on assumptions about production related to a few known dated instruments. In particular, William has assumed an average annual output of 2165 instruments a year after 1908, whereas the more detailed Wheatstone records (from which he has derived his assumptions for Lachenal's production) show numbers fluctuating considerably for the period in question. On the other hand, the Wheatstone figures are for all models, not just anglos. Has any more information come up since Wes's and William's original articles were written to refine these formulae?

varney Posted December 29, 2009 Author Share Posted December 29, 2009 Thank you both, I calculated 1915 after finding the page on the forum for working out Lachenal dates. I thought I was getting it wrong though, and was happy to settle for 1897. Now that I look at the instrument it does have a WW1 / 1915 era look to it! I know that doesn't make sense but it just doesn't strike me as Victorian in appearance. Link to comment Share on other sites More sharing options...
wes williams Posted January 3, 2010 Share Posted January 3, 2010 Has any more information come up since Wes's and William's original articles were written to refine these formulae? The table above is not based on a formula (as in the original article) but on features, dealer's label addresses and repair marks from a reasonable size sample of instruments, so is much more representative of the correct dates.
