St. George -
Bob, those are fine looking. I very much am impressed with the quality of Mr. Burrow's work. He's one of the few who make expensive leather that I feel are actually WORTH the price. I have a nice set of spur straps with a beautiful Sterling Silver engraved concho that a friend made. They are similar in shape to yours, but one main piece and the buckle small section. The bad part is that they adorn my rather cheap inexpensive not-so-good spurs. If I ever win the Lottery, I'll be talking to the Lindholm Brothers, or perhaps an authentic old set.
Shoot, MOST of the time, I wear my Civil War "issue" plain Jane ones that I kept when I mustered out of the 4th Cavalry. (Which in REAL life were earned by me/awarded to me while assigned to Border Duty with the 11th Armored Cavalry in Fulda. They [and straps] came from Fall Creek Suttlery.
