Does anyone know where I can get a copy of R. P. Steiner, "A theorem on the Syracuse problem"?

Question

R.P. Steiner. "A theorem on the Syracuse problem". In: ed. by D. McCarthy and H. C. Williams. Congressus numerantium; 20. Proceedings of the 7th Manitoba Conference on Numerical Mathematics and Computation, September 29-October 1, 1977. Winnipeg: Utilitas Mathematica Pub., 1978, pp. 553-559.

Answer 1

Not sure if this is what you want, but a Google search for "R.P. Steiner. "A theorem on the Syracuse problem"." returned this as the first link:

https://www.sciencedirect.com/science/article/pii/S0022314X06001223

The paper is freely downloadable.

Answer 2

I think there is no open exemplar on the net (I've searched a couple of times intensely).

But the articles of John Simons/Benne de Weger (linked to by wikipedia) from 2000 to 2002 on the $2$-cycle and the $m$-cycle problem refer to it fairly explicite.
Moreover, I've a personal mail of R. Steiner where he sketched his proof-idea for me and it is pretty short: the key seems to be the idea of introducing this Baker-style argument at all. And then the sharpening of bounds by a later author (Mignotte?) which in connection with the continued-fraction-convergents allowed to complete the proof via accessible range of numbers.
