One quick story while I'm between patient appointments. I used to spend weekends with my grandparents (quite a bit, undoubtedly more than any of the other 6 grandchildren). Once on a Saturday PaPaul and I were watching motorcycle racing, and he derisively said, "Look at them putting their foot down in the curves. When I was racing, that was considered 'sissy'." When I said they were probably going a bit faster he immediately retorted,"Oh no, they're not going any faster than we were." I still laugh about that.
We played a lot of pool together, in his later years I would pick him up and we played at the Round Table Club on St. Charles Ave. next to Audubon Park. If there were other players, we would play as a team. The Treens would play against anyone. I still have the cue he kept at the Club.

Regrettably, I spent very little time there. I distinctly remember going there twice, although I'm sure I was there more than that. I'll try to get whatever I can from my father. He has the desk. The "legend" is that there were two made, the other was Walter Chrysler's. I think my grandfather acquired it secondarily, though. I have my grandfather's dining room table and chairs, breakfront, and two sets of love seats + paired chairs, among other things. He had a good eye for quality antiques. The dining room table has 14 matching chairs, and was used in the house on St Charles Ave., as well as 5025 St. Bernard Ave.

The earlier seats, from 1935 to 1939 were made by Messenger or Troxel.  After this, simplex started making their own, and they became bigger.  According to Gay Wollard, the size came from Cyclone Treen's rather large backside!

My father told me he did trace the outline by sitting on a piece of paper or cardboard, but his "backside" was rather normally proportioned for a man of 6 foot height, if anything, a bit flat, a trait I have regrettably inherited.

According to my father, this was quickly abandoned after he visited the Schwinn factory, and reported to his father that there was no way they could compete. I doubt that more than a few prototypes were made. My grandfather never mentioned it to me.
