Just bought my first straight razor

[Deanner]

Hello everyone,
I purchased my first straight razor on sunday at the local flee market. I was looking at getting a dovo but when I saw this one for $20 I thought how could i go wrong. I was wondering if anyone can tell me a little about what i have bought and if $20 is a good price. Here are a few pictures. Does boker make amboss mann or is it a different company? I tried googling amboss mann and didnt come up with much.
Thank-you
