Shaver Buret is from Shaver farms out of the first import Maine bull registered in Canada Buret. Gary Graham owned Buret and selected him in France as a calf. If anyone knows about this bull it would be Gary Graham. Here is his website:

I saw Dollar 2nd in stud at Western Breeders and he was a massive individual being 3,200 LB at the time. He was smooth compared to many of the French Imports at the time and the calves I saw were good. A problem soon reared his head when it was found out the hard way he was heterozygous for double muscling. This effectively ended his use in many purebred herds. His birth weights weren't the lightest but they weren't the worst either. Cows only here.
These were very big cattle; average 100 LB plus birth weights were common in Western Canada on these bulls from purebred and fullblood cows. Your birth weight may be less depending on where you are. The cows produced were also big- 1,750 to 2,000 LB with some larger.
Like many European beef breeds at the time the yearling bulls had small testicles. I have seen Maine Anjou bull sales where they had many bulls not make the sale for this reason.
Red Knight was more calving ease oriented than the above two bulls being breed in Canada. For a Maine calving ease bull look at Coca Cola. For the longest, muscled out, heavy boned and hard calving bull look at Crack.
