I picked up an Old Type recently as well, and took it for a spin yesterday for the first time. The first thing I noticed was the blade alignment was a little tricky and took me a good 5 minutes to get even exposure on both sides. However, after that I was plain sailing and got one of my closest ever shaves. It's also my first open comb so didn't know what to expect which probably added to the quality of the shave as I was super careful and gave it my full attention.
