How long is the barrel? If it is like 18 inches it is a carbine, if like closer to 24 it may be a M38 or something. The carbines usually seem to have the marks of a California importer as they were mostly imported in the 60's long before the long rifles and such. And they were putting barrel extensions on them to get them up over the 18 inch minimum at the time.
Your gun is like your nose, it is just wrong for someone else to pick it for you!
