Te vitomatic 1 camera was the vito b with a built in exposure meter, I have the vito b with a color skoper lens, and it is no mean performer, I suggest that you get hold of a shoe mounted rangefinder, you can often find one for around £5, or $5, the Voightlander cameras are very well built, very solid and dependable, and capable of very good results, In later Vitomatics ( from the IIa onwards) had a built in coupled rangefinder and used the Compur slk shutter which had a top shutter speed of 500, so use and enjoy a vintage piece of photographic equipment
