As they say: Never say never. A friend 2 provinces over found these in the rafters of a now defunct surplus store in Calgary some 30 years ago. Three brand new tires, 2 on rims, and have never been installed on a gun. A deal was struck and they are now in my shed waiting installation. The rubber is still soft and pliable. I am not so obtuse as to ever tow these on my gun into the city, they will strictly be for parade or display purposes after being trailer-ed to the location. I guess I better start making the hitch brackets for my Mk1 carrier.
Almost forgot,I have to weld the gun as well

thanks to the inane regulations of our corrupt ruling party.
