Or the panoramic might fit a frame like this?

It comes with a mat that has 3 cutouts. Either swap it for your own, or trim out the cross pieces.
Overall it can be pretty inexpensive if you can do it yourself. The frame I did above was I think maybe 20 for the frame, a couple pieces of matboard at $6 each since I used two colors. The museum glass was the most expensive bit at around $25. plus some incidental stuff like fishing line to hang the medals from and acid free photo corners to hold the paper items. Even if I had to buy the tools like the xacto knife I'd have been under $100 The whole thing took me a couple hours to layout ,cut and assemble.
