Vintage holiday house trailer air vents

I copied this part from a friend's restoration project of a Holiday House Trailer. They were used in cabinet doors for air circulation. They are not sure if they are original parts or a replacement from the same era. They were badly damaged, so I recreated them to as best of a reproduction as I could. I kept them as two parts for easier/nicer printing and fused them together with Weld-on 3.
