This question about Whittle saxophones turns up on this board from time to time. I've mentioned in previous posts the same info I am going to give you: Most of these horns are Conn stencils, sold by Whittle Music Store in Dallas, TX. Since Conn's records for their stencil horns are no longer available, it would be hard to lock down a manufacture date for this horn based on the serial number. The value isn't great for most stencil horns, but the Conn stencils are usually still nice players none the less.
