I think you’re saddle looks great as is! The scuffs on it should go well with a bike the age of yours. I have a 1975 Raleigh International that I bought used and it came with a Brooks B17 narrow saddle on it. Unbeknownst to me, someone used shoe polish on it and it all came off on my pants. It all came out in the wash (I didn’t think it would). Still, I’m not sure how I’ll get the rest of the shoe polish off of the saddle as I’m not prepared to risk another pair of pants. I love this saddle but I can’t use it. I wish the saddle scuffs had just been left alone. Just my experience.
