Re: Any Hermes saddle. Not that I'm saying you should buy one in awful condition but, you can send any Hermes saddle back to Paris where Hermes will repair the saddle for of course $$$.
Each saddle # is recorded in a book, along with the date made, and the names of those who made that saddle. (And now on line, you can trace your saddle back to the year it was made. Well, I got a nice guy at a saddle shop to find out when mine were made.) I've never had to have mine repaired. But they will add blocks, etc., for $$$.
So maybe a cheap Hermes, with a good tree, is worth the repair cost.
