Differences between 273 Commando Silenced Air Cleaners?

As far as I can find out the Chrome air cleaner only came with out tube. I believe the ones we see with tube is simply a slant 6 cleaner that was chromed. Im might be wrong but the pics I have seen of these restored 273s leaves a lot of questions. 67 valve covers on one so the proof of pics of these restored cars is lacking. The fuel lines are incorect on most so Im not buying the tube is a CAP on chrome air cleaners. Need more proof IMO.

I have had both styles original chrome. They came both ways. I've had more than a few original untouched 273's. Proof? don't know how to do that.
