mjolnir2: I've noticed two with such markings recently- one on gunauction.com and one on Gunbroker.com. I also recall their serial numbers were quite close together. Can you post some photos? Note: found the two sale postings. Both rifles are 1945, serial numbers T33475 and T33439. Again, both have D6E on both sides of the rear of the body.
