While there were a huge number of these cameras made and there are still a loit of them around, eqch year there are fewer and fewer available. I strongly believe that we do not "own" these vintage cameras. My Kodak 2-D is much older than I am by many decades. I view myself as a steward rathan an owner. I am just a custodien of this 20th century holding this camera for someone else to use later on in this new century.

I would clean up both of them and keep them safe for posterity. Another way to look at this , . . . .you have a reason to buy a new camera!
