Now that we know it was a Harmony Model 1, made by Columbia, does anyone know what years they were made?

Maybe I could hazard a guess at 1925-1929, and (if this guess be correct) this might explain why you have found one of the most interesting of the 1920s lowboys: think of it kind of as a "last of the Mohicans." Warning, as I said, this is just an educated guess.
Harmony (with that particular lettering in the title) is on some records in my collection too that were actually pressed by Columbia Graphophone as a "dime store" label, and they sound amazing just like your phonograph will when you have got it fixed up. What happened was, Columbia Records had built a very large new studio with updated and redesigned "acoustical" recording equipment, you know, the old stuff where you recorded through a horn instead of a microphone, but they'd taken that and built probably the world's best acoustic recording studio, ever.
Plot twist: it's 1925. Victor Talking Machine, Western Electric, and RCA have gotten together and developed the "Orthophonic" record which marked the marriage of hi-fi with vacuum tubes (and great expenses.) New records had a wider frequency response and they called for a different sort of phonograph to optimize the sound, like the Orthophonic Victrola with the exponential horns. Viva-Tonal was Columbia's response and it made them redesign all their Grafonolas to keep up with Victor. (Meanwhile back at the labs, Edison is still selling Diamond Discs and Blue Amberol cylinders.)
Columbia had the new acoustic studio but couldn't afford to rip out the new equipment to update it for electricity. However, there was a huge market for inexpensive but good records (a quality acoustic record will sound great on any kind of antique phonograph, from the Orthophonic stuff all the way back to old 1900s models) so with the best acoustic studio around they went to making budget discs. First was Harmony Records in 1925, the last label ever to go over to electrical recording which they did in early 1930.
HERE is where your phonograph gets to be a bit more interesting than the standard 1920s lowboy. The tonearm looks like something you'd get on a Columbia Grafonola from about 1918-1923. That's fine. That was all you ever needed to play an acoustic record and the large reproducers had incredible sound quality (bass response sometimes out-performing an older model Victrola and treble that stayed pretty smooth across the range.) So it was a perfect tonearm for this--like Harmony Records themselves, it was excellence forced into obsolescence. Furthermore, it was cheap to make, lots simpler than the complicated procedures Columbia was doing to make their Viva-Tonal Grafonolas--which was good because a Harmony Record cost about 50¢ and if you built your record collection out of the 25¢ Challenge and Conqueror discs, 50¢ Harmonys, Orioles from McCrory's Stores, and whatever, you wanted a less expensive but good-quality phonograph.
So I don't think it's as old as 1917, or even 1921. It shares parts with the then-costly Columbia Queen Anne. But I think it instead is a value-line piece made to give music to the masses in the closing years of the Roaring Twenties, a reflection of the sea change in recording of 1925, of Columbia's mistake in continuing the acoustic record line. These kinds of phonographs are getting scarcer by the day as, due to a lack of collector's interest, they are being scrapped for repurposing projects or for spare parts. With its post-1925 heritage as a product of Harmony Records, I would say that this is a machine which deserves to be preserved--and enjoyed.
Because all that earlier about Harmony's studio being state-of-the-art for acoustics, is correct. Harmony (and later Diva Records I think; they're laminated pressings which might mean Columbia) have got incredibly clear & crisp sound quality, rivaling some of the Victor Orthophonics of 1926 (Those sometimes hiss.) This is a great find as far as budget consoles go; it should be able to play great with that big reproducer. The silk grill cloth goes on the back side of the grill--a bit of Howards' would clean up the scratches in the finish. If you haven't done the mechanical overhauls that shouldn't be too hard. With this machine you have got a lot of history in a very small package. Good find!
