Hi Mike,
Like yourself I enjoy the vintage aesthetic and use a straight. Not sure if this is the sort of thing you're after but it's what I use, a WW1 British military officers wetpack (replica)

It's very well made and holds a ton of equipment. For strops you can buy roll up ones fairly cheaply that will fit inside the pack , personally I use a small paddle strop. As for mirrors there are some quite high quality “compacts†out there that do the trick or just search online for travel or handbag mirrors.
