Then it is most probably what is called the DSC version (Defense Supplies Corporation). DSC was a government agency, one of its functions being procurement of handguns for essential civilian users, such as civilian law enforcement agencies and defense plant security guards. During WWII, most sales of new guns to civilians was discontinued, as everything was going to the military (also true for automobiles). The fact that your Victory has no topstrap property stamping indicates it was not shipped for military service. There are other possibilities, for example, guns supplied to the Merchant Marine and OSS, which are similarly unmarked. But in the grand scheme, almost all Victories without a topstrap property stamping will be DSC.
