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 Selmer model, but the details are unclear. As shown in the photos, there are spots around the case that look like mold. However, for some reason, there is almost none on the top half of the case, so it's uncertain if it is mold.
