Hi,
A few days ago a friend gave me this old "basto" 
ack saddle he found while cleaning out an old barn.
Apart from being a beautiful piece of traditional craftmaship, it seems to fit Nero just fine so i'm definitely going to repair and keep it!
This kind of pack saddle is still very popular in Italy and has been made for centuries with virtually no changes to the basic design, which consists of a tree made from two wooden arches joined together by 3-4 wooden boards per side, and a heavy straw and wool 
adding, although every maker has his own different way of making it and you rarely find two identical examples.
There are still a few makers that are able to build this saddle to order.
I don't know if this kind of saddle was also made in the US but i guess not.
The "basto" is an extremely bulky, heavy saddle, larger examples like mine can weight 80+ lbs, but due to its large padded weight bearing area, is also really comfortable and allows the mule to carry heavy loads with ease.
The "basto" i have is quite old, probably from the early 1900s judging by the archaic square head bolts used to join the arches, newer saddles also tended to be smaller and lighter and often lack the decorative accents mine has.
It's also a rather well built example, the whole saddle's top side is lined with a single huge piece of soft, strong leather instead of the 3 separate pieces used in most other saddles, and the wooden tree arches are made out of chestnut wood instead of the cheaper fir used in most saddles (which is 
rone to woodworm)
As you can see, both arches in my saddle are broken, likely due to a mule falling over it, i will need to splice them back together, this won't be easy but it's definitely possible.
in this pic, the bolts that hold the two halves of the arches together have already been removed to disassemble the arches for repair.
The front arch has a previous (bad) repair, it cracked along the bolt holes and someone added this crude steel plate to hold it together.
the croup strap is also missing both buckles and is hooked to the britchen with bailing twine, this will obviously need to be repaired too.
