Sorry I didn't help all that much MaconGun because I own way to many 1911 colts it was rather obvious to me,only one of the guns you posted off of GB was an officers model,but colthunter's appears to be an enhanced bright SS MK IV series 80 They do usually bring more $$ than a regular SS MK IV series 80,MK IV commander or even standard MK IV series 80.
They are not actually rare but very uncommon and much desired therefore the increased cost
Hope this helps
