Yeah, it's an old German LUNA from WW1. Quite an agressive shave, so you need to take your time, else it can bite you.
The Gillette 195 Slim Adjustable is a dream. I find setting #4 to be ideal for a twice weekly shave, and the weight and balance very nice too.
If your shaves are a bit further apart, crank up the number. Or if you're shaving more often, you can wind it down a bit.
