Liam, yes and yes and you're welcome / although from the forum, not me, I am afraid I probably did not help
Anyway, if Mauro or Vlim sees this, they can tell you exactly when it was made! I have an American eagle model 4 inch, I hunger for the 6 inch now. Darn things
There is a tutorial here on the forum, explains leather well.
Personally, some saddle soap (always go light on everything) will clean it up, then I use leather conditioner, do NOT use anything you'd use on boots as it softens the leather. You must use something made for it. Some use Pecards, but it leaves behind a gooey residue and I won't use it anymore. I use Connolly's and bought it off of ebay, it is used for Rolls Royce seats (made of leather) to preserve them, us it light and sparingly and then rub it shiny after an hour or so.
It WILL darken the leather, that said, it evens out the scuff marks and always makes it look better, but if it that really nice lighter tan or brown, it will make it darker.
