Welcome to SRP.
In my opinion I'd take some steel wool 000. And some metal polish and try to get the black or red rust off of both of them. Careful as it only take one slip and they can take off a finger. Then just put them away or in a shadow box. They both need work to be up to shaving duty and they both are slim razors now so fixing them up is really not something I would recommend. Keep them knowing where they came from. Then pick yourself up a couple razors to learn to shave with. You can find some in the BST thread. But to spend time and or money on those is really iffy. JMO.
