Thank you Neil for useful post. I found supplier who sells swedish bridle leather and I am going to see her tomorrow. Learning some leather working techniques same time and going to choose few good hides also for first strops.
I don't like idea to waste over 50% of hide because it is not good enough. So now I have to think what else I could do with parts that are not suitable for strops.
While there,ask her if she has any Swedish single bend,That is some fantastic leather.Good luck.
