wes williams Posted November 2 Share Posted November 2 Its taken nearly 20 years, but an update to my Serial Number Muddle in Early Wheatstone Ledgers (2005) has finally been put up as The Earlier Wheatstone Ledgers - A Bigger Picture . Sorry for the delay!! Everything in the 2005 version still remains valid. This update covers 1834 to 1913, with data from all the 'Wayne' sales ledgers, and with 'Dickinson' ledger SD01 up to the end of 1913. It includes some suggestions on dates for missing numbers between 1848-1851, and 1891-1910. If anybody wishes to dig deeper, I can produce more graphs of smaller periods if you PM me. 2 Quote Link to comment Share on other sites More sharing options...
d.elliott Posted November 14 Share Posted November 14 Thanks Wes have a family instrument. an Aeola, serial 23182. I had it pegged at 1904 (ish) but this data would suggest around 5 years earlier about 1899. I can understand that the 'scatter' is the result of instruments being batch made or even re-sold/ exchanged etc. but I am intrigued to know what happened in 1866. Equally , no production between 1849 and mid 1851, very strange indeed. Quote Link to comment Share on other sites More sharing options...
wes williams Posted November 15 Author Share Posted November 15 Dave, Serial 23182 is 1901 on the line I drew to join mid 1891 to mid 1910 - the gap between the ledgers that have survived. But if your aeola is octagonal then we also have Kenneth Chidley's statement (Edward Junior's son) made in the mid 1950s -'The aeola, in its present form, was produced by my father in about 1902'.

d.elliott Posted November 16 Share Posted November 16 Hi Wes, I got my (new) PC repaired, and have just seen your response above. My Aeola is octagonal, metal ended, no air release valve but the ends are pierced for a lever type release mechanism. My line that I drew used a curve from the end of the 1991 plots to start of the 1910 plots. so I can see how a discrepancy in approximations can occur. Chidley's statement is not exactly absolute. but it is all best guess and best efforts when we are without the missing data. Quote Link to comment Share on other sites More sharing options...

According to Harry Minting's data 23000 appears to have been made in 1901, and 23499 was made in March 1904, so 1901/02 sounds highly plausible for 23182.

d.elliott Posted November 17 Share Posted November 17 Possibly, but still played regularly, if not well. Quote Link to comment Share on other sites More sharing options...
