I trapped one on the farm when I was 17 that weighed 113 lbs. When I skinned it out and put it on the beaver board it was 2 inches bigger all the way around on the board than the largest ring. I had the marks drawn out on a 4'x4' piece of 3/4" plywood and I actually had to redraw the ovals on a 4'x8' sheet because it was over the edges on the top & bottom. i had a proffessional trapper help me with this so it was not like I had stretched the cr@% out of it. I will have to find the picture and scan it. Sadly I sold my prize catch and have regreted it ever since
. I have been looking off and on for the past 17 years for another that size to put on a willow hoop but, to no avail.
