My kit back in the day wasn't much different from yours. BTW, I'm envious of your adjustable spanner! Mine was a cut-down 10" Sears Craftsman to fit in my Cannondale 'Toot' seatbag... Multi-tools weren't popular 40+ years ago, so I carried a 6mm Allen, two screwdrivers - (one flat, one Phillips - although later two of each but the full-size were of 'stubby' length) my patch kit, a spare tube, spoke wrench, freewheel remover tool, chain breaker, and my full-size frame pump. Oh, and my pocket knife.

I now have a multitool (Parks I-beam model) with a chain break. I only carry the adjustable (6" just works on pedals) when I'm going to assemble/disassemble at the termini. I carry a cassette tool on longer trips. And a small roll of duct tape, of course.

The bike always has one spare tube, patch kit, multitool, and tire boot. On tour I add another spare tube, spare spokes, a couple of 5 mm cap screws, and a shifter cable.

Last month I posted a couple photos at this link from my most recent tour with my S&S coupled bike that has a Rohloff: Instead of re-posting it and re-describing it all over again here, just providing the link instead.
Mechanicals on tour

Being a Rohloff and not derailleur bike, tools were slightly different. And being an S&S bike where you have to almost completely disassemble and reassemble the entire bike at the start and end of tour to take on a plane, I bring some shop sized tools to make the assembly/disassembly easier and faster to perform. The slight weight penalty is worth it to reduce frustration.

I do not have a good photo of my derailleur touring bike tool kit, but at the link above I listed the differences in tool kit parts.

Every tour I seem to bring a different set of tools. I don't have a photo, but this is what I brought on our summer trip up the Blue Ridge Parkway:

1. Fix It Sticks tool with only the bits to service our bikes
2. Fix It Sticks chain breaker (this thing is as good as a shop tool but still compact)
3. Park No. 0 spoke wrench
4. Tubeless tire plugs and insert tool (both of our bikes were set up tubeless)
5. Spare tube
6. Pump
7. Rag
8. Chain lube
9. Spare Shimano 11s quick link
10. Pedros tire lever (the best)

The only mechanical we had mid tour was a slashed sidewall, which I fixed with a dollar bill and the spare tube. The Fix It Sticks came in handy for (un)boxing the bikes. I don't think we ended up using any chain lube because both chains were new at the start of the trip.

I continue to be impressed with the Fix It Sticks tool. It works like a dedicated shop tool but is as compact as a lot of multi-tools with inferior functionality. The only downside is the potential to lose the removable bits, but with care it hasn't been a problem yet.

Older picture, more details here. Nowadays there is also a Park Tools CT-5 chain tool in here.
