Hi Bruce ~ I wasn't aware that the more common horizontal slide was available on the A-250.
I don't actually know one way or the other, but I would have assumed that the more commonly seen horizontal lever style wasn't used until after the standardization following the factory fire and would have thought that this didn't appear until the machine was renamed B-250. When you mention having seen later examples of the A-250 with the later style tone lever, are you sure that these were A and not B series machines? Anyone out there have an A-250 with a horizontal tone modulator lever? The tone modulator on my later A-250 serial number 13417 is the same as yours; i.e. it lifts straight up and can be leaned to the left to reduce interference with the lid. What's interesting about learning that your serial number 10248 machine also has this feature, is the fact that our machines are some three-thousand (3,169) numbers apart, and yet they both have the tone modulator. If the source information that Frow used on the date of introduction of this feature (November 1914) is correct, and your machine was made (for example) the first week of November, and mine the first week of December, and the factory burned on Dec 9, this would tell us that the production per day of the A-250 was approximately 105 machines. This assumes that the November date of introduction of the modulator (which is not given in Frow) was near the beginning of the month, and that the production had achieved 105 machines per day of that one model by late 1914. If this daily output of A-250's matches up more or less with established data, then we can really pinpoint the date of manufacture of any A-250 equipped this way to within a week or two in 1914. This also assumes factory equipped and not retrofitted. Does anyone out there have a sense of whether this daily production quantity is realistic at that time? Any other comments about this?
