If you never had an issue with your old saddle why not simply buy a new saddle of the old one?
Some people have recommended Brooks and those are very sweet saddles for comfort especially the B17 for touring because it's designed for a more upright touring riding position; another option is the Terry Fly which is another commonly used touring saddle.
If you decide to go with the Brooks there are specific ways that saddle needs to be treated you can ruin it rather quickly. First off, don't listen to anyone on how to care for it or break it in, because there some dim wits out there who act like they know what their talking about but when it comes to leather saddles they don't have clue. So does that mean that I'm the foremost knowledgeable person on that subject? NO! But I can tell you who is...Brooks is! Yes that's right the manufacture that makes Brooks saddles has been making them for over 100 years does have a clue on how to take care of them, so if you want your warranty to remain intact and you want your saddle to last a long time then do what they say and not what someone else says because if you try to speed up the break in process by soaking the saddle in oil or water or some other such goofiness your warranty will be voided and for good reason. The only three things I do differently from the instructions, but mine's out of warranty so it really doesn't matter, is number one, I don't turn the spanner nut as much as they recommend, I only turn it a 1/8 to 1/4th a turn about once every 2 to 3 years not every 6 months, but the weight of the rider does play into the frequency issue. Number 3 I don't use Proofide much only once a year, in fact I didn't use it at all during break in because I wanted it to break in slower for a better fit, like shoes. And number 3 I use neutral colored Kiwi shoe paste wax on my saddle because it seems to repel water better than anything else I've found. None of those 3 items will void the warranty anyways, but using any oil based products, or water based products will void the warranty. Those Brooks saddles are to be a hammack for your butt, it's not a glove or a shoe, thus it has to support your weight, if you oil it the saddle will soften too much, which can happen if you overuse Proofide too, and then you will have to keep tightening your spanner and eventually it will run out of space to tighten any more, or it can rip the rivets out of the seat.
