I wear MH71 5.5E and 888 5.5D both oxford style captoe. I have relatively high instep, small heal and narrow ball joint. I think my size on 82 is 5.5E. Never tried 5.5D on 82.
I have derby (Hove) on MH71 too, it feels less snag around instep because of design. so it largely depends on model and style, but I recommend the same size for 82 and MH71 in general.
82 toe box is curvy to inside so if you do not have an issue of pinky touching with 82, I think you should be OK with all GG last with the same size. I hope this helps.
Thanks a ton. That's enormously helpful to me! It's good to hear from someone who's even remotely close to the same size as me. Thanks again.
Damnit! If only the June shoes were in MH71 or DG70, I would snag one right now!
