I'm on the fence with this one. It looks like the regular RDV5, but on closer examination it could be the RDV6 with slightly overpolished parts.
There appears to be a "chin" on the G and perhaps part of the horizontal lip.
The middle arm of the "F" appears shorter than top arm also.
I'm leaning to RDV5, but thought I'd get some second opinions before I tossed it back into the spend pile.
