I show the 717 starting in 58. Do you have evidence they started in 57? That would be the first block pre-58 to have the Dowel then.

I have never seen the Jim Carter numbers or the 923 but that doesn't mean anything. Which ones do you have or have actually seen Tim? We should keep an eye out for people with 261's and see what they have.
