Let me put my opinion in here. Yes that is my vent and it is no longer made or available. It was machined from a solid block of aluminum and made to a very high standard. When I retired my vent guy did too so once the supply was gone there was no more. I have a couple of them and have been thinking about contacting Steve Melton about making them. When that vent is placed in the right area it really works well. Larry Vetterman
