Since you have them (1264/1265), if you have a gross micrometer or OD gauge, measure the groove diameters of the 1217 and 1265 and determine the groove diameter difference to see if the same or diff rings are needed. I'd check mine but I won't have access to the said devices until Mon-Tues-Wed. I am SUPPOSED to be receiving 2 new queens for a couple of my hives "Monday or Tuesday", so I won't be heading in to the shop until after the queens arrive.
