What years had a cast iron steering wheel spider with double keyways? I have one and am curious about using it for my 15.
The spider for 1915 is a forging. The pressed spider didn't come along until 1920. I've found the double keyway in 1915 steering columns, so I think you're good to go. Of course, the judges will never see how many keys are in there.
My 1914 is double keyway also
If I remember right, my 13 did also.
Here's a double keyed '15 column
It could be a forging, it certainly isn't stamped
