I would check with Rich. I think a while back they did a full art package sale. When I got my Swimmer it needed a new CPO, but it wasn't on this old game's site anymore. But I contacted Rich and he was still able to print one for me. This was like an year and a half ago though.
As for the side art, at point I was talking with coinmunchers on ebay because he was selling reproduction Swimmer bezels and he had mentioned to me that he did the reproductions of the side art. I just tried searching his username and it's currently bringing me to an error page.
