Len, that is why you should buy my Simson book
MANY lugers were refurbed and also about 12,000 were newly made. The following things are to tell the difffernece in new and refurbed:
1. Acceptance and proofing on right (should be Simson markings)
2. Simson acceptance on almost all small parts
3. Either no suffix or "a" suffix on front of frame, no other suffixes are correct
4. Stock lug should be marked with either E6 E6 or E33 E33 (although one E6 E7 is known)
