Given the pics provided, I would say yours is the normal RDV-005. Look at what coop told you but my go to is the G, in FG. The vertical serif of the G sticks out past the upper part of the G, to the east. I do agree with you that the RDV-006 is unmistakable though. Clearer pics may show me something different but I don't see RDV-006 on yours, as is.
