A near PWC headquarter mystery

The first car seems to be an Austro-Daimler ca. 1912 (from Radiator, bonnet and front springs)
The seconsd car is a Benz 16-50 around 1925

I vote for Graf und Stift. One of these bloody mysteries has to be a Graf und Stift at some point.

In my opinion both cars are Benz. The car with flat radiator is slightly older (around 1912-1913) than the one with the pointed one (around 1914-1915). The older car looks rather battered and misses the usual louvres on the bonnet, but it appears that it has been replaced by a new one: notice its shiny (bare metal?) appearance. The photograph is obviously much younger than the car: judging the clothes of the people in and around the cars, I would estimate the mid-twenties.

I'd say the first car is a 1912 22/50 Mercedes

and the second is a 1920 Benz see:http://www.svvs.org/genpics12/1920_Benz_E6_Touring_Car.jpg

second car is a Steyr

My guess is the pre WW1 car is a shaft drive Benz, and the 20's car is the Mercedes.

Interesting photos!

I think that the first could be a big Lorraine-Dietrich. The second is a Benz
