One from a D might fit. Or an MX-EVS Automat?
Although the holes and back section are consistent, the front section that goes behind the nameplate or meter cell block varies. I don't remember the pattern I found years ago, but do some checking!
By the way, the hood you show in your photo is not the stock C hood. That looks like an MX-EVS hood? If it functions smoothly I would not bother changing it. A clean hood will be silly expensive as with most Rollei parts, and your hood has a nice look.
