I question the serial number for this one - it would put a 230 before the 201, which strikes me as improbable. I thought the 230 was contemporaneous with the 240 tenor, which came out in the late 30s or early 40s. The second digit of the serial number in the photos is unclear - could it be a poorly struck 4? A serial number of 140950 would make more sense.Another '230' alto for the list SN#110950. Good photos.
