Judging by your pictures it is not an E-M frame. I agree with the others that it looks home made. E-M frames were made of round tubing and ones with VIN's had 1" X 3" tags rivited onto them. The VIN usually began like EMSC427. They were not stamped on the frame as far as I know. I hate to tell you this, but your manual might be doing more harm than good. Best of luck to you!
