Davem,
Most folks are confused by the term "money belt". Original money belts of the period, were not intended for paper money. They were used with gold or silver coin. These belts were made in several standard widths. The one I offer with a single row of cartridge loops, is a 3" wide belt. I also offer a 4" wide belt with a double row of loops. The 3" as shown in my photo, starts out as a 6" wide piece of li leather, folded over to create a 3" belt. Billet, buckle end and cartridge loops are sewn to the face of the belt. Then it is folded over to make the 3" width and the main seam is sewn along the full length of the belt. This forms a hollow tube the full length of the belt body. There is a slot cut in the belt through both layers, under the front edge of the buckle. Coins are dropped inside the belt through this slot.
Spur straps can be made in a variety of styles. The ones in the photo are most often referred to as "Gull Wings". They are one piece, without a buckle. These are my spurs and I prefer the gull wing pattern, so that is the style I made for this pair of spurs. I like these 1870-1880 style spur leathers. The silver conchas do not have screw backs. They have a heavy standing loop soldered to the back, which is also made of silver. There is a short tear drop piece of leather cut to fit the spur button, which slides through the standing loop and riveted to the strap under the conchas. Unless you are familiar with this type of attachment, this will be very difficult. If your spurs don't already have metal chain hangers, I don't see any way to install them on your spurs. Hangers are attached during the manufacture of the spur. It is attached before the button and stud are put on the spur.
