The C melody horns just before and just after the serial number in question shown on Saxpics all lack the spoon alternate F#. The apparent thinness of the bell could be more pronounced by the angle of the camera shot as well. If the OP can measure it from top to bottom without the neck attached, that of course would be the clincher. I think it's going to be closer to 28" than 25", but we'll see.Correct on the year. Although the fork F# looks like a tenor, the bell looks more C Melody in the photos. Which is it? C melody body around 25" whereas a tenor is over 28".
