Out of the 300 or so razors I have, this is one of my best shaving razors. If you see one I would jump on it.
Yes, these are great razors. Made by Merkur, they were also sold under the names of Weck, Merkur, Adams and Landauer. I've 2 of these under the Weck name and the Adams name. Damn fine shavers these razors. They all look the same except the Merkur and Weck. The Weck version has "WECK" on the head cap. The Merkur version can be seen below....
I should also note that the Merkur branded version is not an open comb like the Grafco, Weck, Adams and Landauer branded ones.
