High-back trouser pictures

Could not find the past thread which dealt with this topic...I am posting pictures of some of my english back trouser pictures as they differ stylistically from those previously posted pictures...these have no visible external waistband(although there is one on the inside)..also, these have a higher back...buttons on the inside on the front, outside on the rear..also, demonstrates examples of Thurston's "X" back and "Y" back..
