The early 70s V7 Sports have a frame part number stamped on the headstock - DGM4104OM, a part number they all share. This is on the right side of the headstock and is visible next to the VIN plate
It is not unheard of to select DGM4104OM erroneously as the VIN for some V7 Sports being resurrected after long term storage and separated from their titles.
I know this to be a fact because my 1973 V7 Sport lingered over 30 years in a barn before surfacing. The fellow who found and resold it to me selected the frame part number DGM4104OM as the VIN when re-registering it in Ohio.
I corrected this mistake with the help of a knowledgeable Secretary of State police officer and received a proper title with correct VIN soon after I purchased it.
Not long after this episode I was admiring an amazing example of a V7 Sport located in AZ on eBay. It was perfect in almost every regard,
except for the VIN that was listed -
DGM4104OM!
Since this was a serious misrepresentation of the bike with worldwide exposure, and could possibly lead to future legal trouble for the seller, I politely informed him of the error relating my experience. I advised that looking out for his own benefit he should have the VIN corrected before selling it. He told me to stay out of his business and threatened to send a local convincer to my house if I did not. A gracious response if there ever was.
