I've had this Luftwaffe 2nd Model Dress Dagger for 20+ years. When comparing it to others online or eBay, I noticed it does not have any factory engraved marks on the base of the blade. Some I've seen do, others don't. Does the fact it has no markings mean it's a reproduction? Or did Germany produce daggers without markings? Please let me know, thank you. Sorry I can't add photos, the file limits of this site are too small.
