National Primas

Probably Japanese related to the mushrooms but absolutely no proof. Almost all came from Canada, hence the "Canadian type" name.

Your quick!

We all need to stop thinking that Germany did not import toys and Marbles into the USA between 1915-1935. Germany was the main importer of toys of the USA during these years there was only one year during WWI where no toy Imports were brought in from Germany. Here is 1928 and 1929

Here is a similar old American book from 1973

Mine is hanging on the wall with a bunch of other boards

Wish I could stream some molten glass into a spinner cup to see what happens. It was also explained to me the "rod" was an improvement on the original patent so it would not be described in that patent. And the first corks before the "rod" were the kinda corks that many Ade types look like

You all may have me convinced there was no "rod" it just seems that the stream would have twisted around not necessarily corkscrewed without something providing resistance. And what also explains the dark area and occasional twister like pattern down the center of some corkscrews? It was also explained to me to "rod" was above the shears

I am not sure the item with the hole in the center is a spinner cup.

One of the most important parts was the metal rod the glass flowed down under the orifice. This gave the stream resistance allowing it to corkscrew. Some transparents, especially the Reds, show a dark pattern down the center of the marble. Probably oxidation off the rod. I believe the early kinda corkscrews (Ades) were probably made before the rod was part of the process

☺️Here are a couple commercial versions

David made the one with PeeWees special for Landon

I am not sure, need more and clearer pics for these old eyes

Yes Brian I believe I have it in a 31 catalog
