Mark Mayfield emailed me a picture of Bill Stine at the opening of the display of the G. Harry Stine collection at the Seattle Mueseum of Flight (thanks, Mark).

The tower in the case is the metal type sold by MMI. My understanding is that with the demise of MMI, their remaining towers were sold to Estes who included them in the 1961 catalog.

Note how the tower in the case has a square bottom, but the tower pictured on the cover of Mechanix Illustrated has a triangular joint at the base, presumably to adjust the tower launch angle. I presume the one being advertised by Estes is more similar to the one on the MI cover since the ad mentions it is tiltable.

The wood tower I have is 6 levels instead of 7, like the MMI tower, and is not adjustable in any way.
