Here's all the cane I got that size range.
I have not actually spined these but I was making arrows 40 - 50 spine and these where all slightly larger diameter than what I needed, so they should be about what you're looking for.
This cane was cut just about one year ago and have been stored in an open shed ever since.
There's 27 pieces here but quality varies and some are pretty crooked.
I didn't have time this morning but I can go through them better and note how many are good ones and how many are mediocre
