I can send you a scan of the Dan Wesson manual if you send me your email. You'll need a feeler guage and Dan Wesson barrel wrench. Do you have these items which originally came with the revolver??

Impossible to answer without the serial number.
This is for SMITH and WESSON firearms.
357CTG means that particular handgun is chambered for the 357 magnum cartridge.
