That's a really nice looking saddle for an auction saddle! I'm jealous! I always look for stuff like that to fix up and sell..
Girl, the things you can do with that are awesome.. Even if you wanted to get a plain head stall and bling it up.. Where to start!?
All of the conchos on the saddle should be removable because they are screwed in. You can check out Conchos.com IConchos, Guaranteed Lowest prices on our Wholesale Conchos.
and there are a TON to pick from that you can add to your saddle. You can also replace the silver pieces where the back cinch should go.. I'd change the rawhide stirrups out to aluminum and it'll add a lot of look to it too, besides the aluminum being better anyway..
I do like the first headstall the best and love the breast collar.. You can REALLY jazz that breast collar up. You can get the same conchos that you are putting on the saddle, drill a few holes in the breast collar and add the conchos to it to make it match your saddle..You could even do this with a plain headstall and make EVERYTHING match..
Then! Once you get all of the stuff you like together you can even add crystals to the conchos and make it blingy..(I'm all about bling ;) )
You can't really oil the underside too much to mess up the rough out, when cleaning the rough out just use a really watered down soap and a brush..I've just heard of cleaning the ostrich seat with a wet cloth then adding a conditioner, it's a skin, it needs moisture just like leather with oiling.
Like I said, there is a TON of stuff you can do to really make your saddle and tack your own.. If you have any questions at all I can probably help. I bling out a good bit of my tack and it's so much cheaper and easier than paying a lot for custom sets.
