Was the Purple Heart ever awarded with a V device?

I'm putting together a rack for a friend who located some ribbons in an old shadowbox. The service member is definitely a Marine and Vietnam veteran. Among the box is what appears to me to be a Purple Heart with a V device. Eggplant with white on each side and clearly not a LOM. I haven't been able to find any evidence that the criteria for a V device was different in the past and it's my understanding that the Purple Heart does not fit within the eligibility for a V device.
