This is a case for a Selmer tenor saxophone. The striped pattern in one of the photos is not actually present on the case. It was used to hold a Selmer Mark VI (pre-Jubilee) tenor saxophone. The case is of an unknown model, and some have suggested it's for an older instrument, but the details are unclear. As you can see in the photos, there are spots that look like mold around the edges. For some reason, the top half of the case is almost completely free of these spots, so it's uncertain if it is mold. The price is set high, and I don't honestly expect it to sell, but if anyone with knowledge of these cases is interested, please consider purchasing it.
