Ken,
I know Elard liked the idea of the straight-line machine, but he mentioned it was too expensive to make at the time. I don't know the timing of when it was produced, as it was before I worked there, and I did not ask.
The non-universal machine was called the "progressive", and was the first version produced, according to what I remember of my listening to Elard.
They also produced about a dozen or so multi-stage presses. They did not use a rotating shell plate, and had 7/8-14 holes for the dies. The rounds were moved from station by hand. The primer magazine is a horizontal (formed) square tube, with a slot on the top side for a follower, and to let the gasses escape if there was an accident (it works...). I have one, and the parts for a couple more. I converted mine to use rcbs type shell holders. These were made prior to WWII. Elard indidcated they were trying to make a less expensive loading tool, by did not sell many.
I still have a data sheet for the shell plates. I'll find it, and post the calibers listed here.
all the best,
Mike
