To add to the above posts...
Hawes was in-fact the importer for JP Sauer and Sohn, (later became Sig-Sauer).
They made decent quality stuff but never flourished on the market.
Grab them when you can, they will never make you a millionaire, but will be able to shoot like one!
I got a Marshall .357 some years ago. My Son thought it looked neat and I figured it would make a decent plinker for him when he grew up. The Owner practically gave it to me since it had a broken rear sight. I Repaired it myself and took it to the range for kicks. I was amazed at the groups I got with the thing!!!! It shoots as tight as my Python, sometimes better.
A well spent $125!!!!!!
