I have a U.S. Revolver Co. 38 S&W top break revolver. It has approx. 30% of the nickle finish remaining but is not pitted. I am not really interested in the value of this piece as I know it will be low. I am more interested in information about it. Serial # 7293
1) When was this revolver made?
2) Is this a blackpowder or smokeless era revolver?
3) While looking for ammunition I was told that most revolvers chambered for 38S&W are not safe to shoot. Would this gun be generally be considered safe to shoot? I understand that other issues may make mine unsafe to shoot.
Thanks for any information you can provide.
