This post says that he got in touch with the owner as recently as 4/6/11. So I guess he still has the 16mm.
His contact info: emailWell, Chuck it looks like I solved the film problem too! I finally got in touch with Joe McGloin at Goat Hill Photo by email. I just sent a money order to him for 3 cartridges. So hopefully soon, I'll be ready to start shooting some pictures with this very cool little camera!
