Some M. P. Davis, Part III: Some Master Patterns

With the caboose kits featured in part II of this brief series were three envelopes with master patterns for sand casting.

First up we have these passenger car ends for a heavyweight passenger car. These both appear to be Nason parts, one in bronze and the other in aluminum, and he seems to have used these to have another run cast for his own uses. As always, click on any photo for a better view.

Next up we have this passenger car diaphragm. Is this the master Nason used? It really could be. The part matches my Nason parts and Davis is said to have been a silent partner in Nason. He certainly sold some models based on their parts after WWII. The wood part seems to be something necessary for setting up the core box properly, and note that the middle of the part is solid. The part itself is nicely made from brass stock.

The last envelope includes car ends for a troop sleeper. While Graceline produced parts for this model, it was never produced by Nason or Davis, so it must be for a car that Nason or Davis were considering producing. It is wood and nicely made.

This is the back of the pattern, with his handwriting visible. If we had the original master patterns for the other large castings I suspect that they would also be wood patterns.

To close we have this one other part of mystery. Simply marked “California car” it must be a master for a part of some other project that never made it to production. Perhaps a streamliner? Your guess is as good as mine on that. [UPDATE: See the comments for more].

So much OO history is slipping away, but I am always hoping that others out there who either follow or have stumbled upon this website will jump in and also find this vintage equipment interesting.

"California Cars" refers to a type of streetcar, half enclosed, half open. The famous San Francisco cable cars are "California Car" design. The body style was so named, as due to the California climate, half open half enclosed cars were very popular there. The pieces look about like the cross section of the enclosed half of the car. Did anyone produce a OO scale streetcar? If not, then likely these were part of a production sample that was never made. Real history!

Interesting! No streetcar was produced in American OO so far as I know.
