SLR brakes came out in 1987, so it's no older than that, assuming they are OEM. Miele added pump pegs to all models in 1988, so that should make it a 1987. There were two Miele models with SLR brakes in 1987, but those are the Light Action calipers, so it should be a Miele Alfa. Checking the literature, it does show that it was available in Ferrari Red. Pending further evidence (such as a serial number, which is typically on the back of the lower seat tube and the seat post diameter), the best candiate would appear to be a 1987 Miele Alfa.

BTW, while Miele did often spec chrome forks, I question this one being OEM. It's unusal to have eyelets on the forks but not the rear dropouts.
