It is an old Rolleimat Universal. Here is a pic of it with the paper and developer. Despite being oxydised the developer worked quite well (1+4 dillution).
I bought it for £8 and i also bought the Minolta C.E 50 f/2.8 to go with it.
I have it in the garage so i print only in summers when the weather is nice. In winter the temperatures can fall below freezing.
