Thanks for clearing that up. Only one built - kind of interesting piece of information if you look at all the RC models of it that has been built (must be hundreds).

A small five-way, however, seems to be eligible:

Note here the small opening at the back underside of the cowling, just like the four openings for the exhaust pipes. Which is what today's discussion started off with.
Back to you, Jim...
