We`ve got one of the Bigger versions,for Jimmin heavy gauge rails,60lbs`ers,2ft 6in to 3ft across,
You Northeners must have big B---s ,its a Heavy ******,
The one in the photo ,looks like the Medium-Normally used Jimcrow,as we`ve got a pair of the Small ones,just over 1ft across,but the frame seems more rounded.
