Here it is as I purchased it. A bit tarnished but everything was there. The only defects were one tiny ding on the bell and one missing knob on one of the Bb slides. It looks like it was used for a few years when new then put away in a closet until now.

Here are some views after an hour of polishing. It's currently set up to play in C.

The original grease cup.

Here is an interesting and rare Wonder-Tone mute that came with it. This was patented by Joseph Rudick of Akron, Ohio in 1922 and probably built by a local factory.

The original case in about as good of a condition as possible.

Here is an illustration from the 1926 catalog and showing the same finish E. From my research, the model 13 ran from 1924 until about 1933. It changed to the model 210 in 1928 but probably fell victim to the Depression and was phased out.
