I've finally gotten a vintage adjustable. It looks like the doors work okay, and I've given it scrubbing bubbles so it looks worlds better now. I got curious and popped a blade in so I could see the action. It turns easily, and clicks firmly into place at each step, but the blade doesn't look like it's changing angle from the side. Are the changes in position as visible on the Gillette adjustables as they are on, for example, the Futur?
