Upper is fully numbered - matching numbers - "20". Frame has another number (see previous post), but some small parts (locking bolt, trigger) have different numbers, some has no any number (magazine catch), some was evidently renumbered to match frame (safety catch and bar from "33" to "73", overpunching first "3" by "7". Font and size satisfy factory punches. Grips look replica.
