Linotype Mixer?

[Mechanic]

The following web site will take you to a 1915 publication of The Book Of Wonders and a description of how the Linotype works. The Linotype illustrated  is a model I have not seen before. It appears to be a mixer that requires the front of the magazine to move up and down for mixing along the lines of the model 25.

The model pictured is a Model 9, which came out in the 1920s, I believe. The magazines were in the shape of parallellograms and possibly contained their own verges/escapements. The mats had to be cut to run in a certain position in the machine, and couldn't be interchanged. The operator could mix from ALL FOUR magazines, because distribution was simultaneous. A version with four auxiliaries was the Model 24. They were rather challenging to maintain.
F.R.  Edgecombe/Printer of Kalamazoo at one time owned two (2) model 9s, and in 1951 I got to set a paragraph on one of them.
In the late '70s he had downsized to a typography shop (for printers who had disposed of their hot metal equipment) and was setting a large ad in Memphis when I visited his rural shop--despite the inroads cold type had made in the industry.
I think the Model 9 had at least five (5) distributor screws.

Thank you  Patrick, As it turns out there was already a photo of the model 9 in the photo section of Metal Type. I must have looked at the photos half a dozen times in the past, but it didn't register. I agree they must have been a challenge to maintain. I would have loved to have had a go.

Here it is, the picture of the Model 9.

This little puzzle was a lot easier to resolve than this one:

Which still seems to have most people baffled
