Are these 911 brake parts?

[erco]

I am going through some of my dad's old parts and found the ones below without part numbers. The calipers look to be 911 calipers, but the master cylinder doesn't look like anything in the parts manuals. Any help is much appreciated. He also had parts from other models, up to the 944 (914,924,928), so maybe one of these goes to those models?
