I think It looks great the way it is. Clean it up rub some oil on it and you got a good blue collar workers gun(you know a "Soldiers Pistol")Just the way I like em. Most likely a well used historical war gun.
But if you want to learn it some manors and dress it in a tux? That's ok too.
The pictures do the gun too much justice. In person and natural light it looks ROUGH. And it's bare metal in too many spots--I'm in the South, and I have to go back every couple of weeks and scrub some surface rust off. Nio, this baby needs to be protected.
