Quote from: AE_Collector on February 26, 2017, 07:48:51 PMYeah, these posters and advertisements aren't made for us who are trying to pin dates down with some level of accuracy. But then phones weren't like new car models with the new model year all being launched in September of the previous year. There would have been a period of time that the phone was in development, then likely limited supplies of the new models shown around in advertising and industry publications, finally full production and then a bit more time would go by before they actually began to be installed in any quantities. Thus a year or more variation in the dates of introduction is probably normal.
QuoteAs for the Strowger 11 Digit Stick and Wall Set shown bottom right of the "Evolution of Strowger" poster with 1907 under them, I have normally heard 1905 for these but maybe one came before the other? The "Strowger Progress" chart shows a picture of the Stick with 1905 but the text doesn't really talk about that stick design specifically. The "Telephones of Yesterday" poster shows 1908 for the Stick but has a picture of the matching Wall Set with a coin collector dated 1905.
QuoteI wonder why on the "Telephone Engineer" advertisement they have the AE1 and AE2 clearly labelled yet the AE3 and AE4 Wall sets are just labelled as wall sets without numbers. Like they hadn't decided on their model numbers at the point in time that the advertisement was put together. And where we know the AE1 with no provision to mount a dial as an AE1 and the version with a dial or dial blank as an AE1A, they have called them both "Desk Set #1" but added the word Automatic or Manual to each.
Quote from: Jack Ryan on February 26, 2017, 08:54:14 PMI really don't understand that point of view. I get a similar response when asking about the release dates of WE equipment - "it was not the same for all operating companies" etc.In my view, a telephone is either released or it is not. There is a formal announcement (not futures) which may or may not coincide with full production. If not, the statement generally indicates when the item will be available. It stands to reason that installation times around the country will vary.
Quote from: Jack Ryan on February 26, 2017, 08:54:14 PMSeveral Monophones did not have an ID when first released. For example, in 1926 the AE 5 was called the AE 1 with centre stem for manual service.
Quote from: AE_Collector on February 26, 2017, 09:56:40 PMPossibly a move simply to eliminate confusion....or maybe just a necessity to further determine how their model numbering would work. A phone (AE1) that looked significantly different from another phone (AE1A) and didn't have the ability to be converted to dial operation like the AE1A, shouldn't be the same model. Of course the AE21 continued to have both a wall and a desk phone with the same model number.
