I said I would post shots of some of the rigs we used in Washington and the Columbia. These all are pre-tied, but they can give you an idea of what was in use 20 years ago.
This is a shot of one corner of my spinner box. While I did use pre-tied rigs, mostly I tied my own using Winner and Lil' Corky floats from Yakima Bait and Okie Drifter bodies from Luhr Jensen.
The Spin N Glos above were deadly used ahead of a bead (for a bearing surface) and a crawler. They come in well over 100 finishes when you combine wing color--white, black--silver mylar, pink mylar and chartreuse mylar--I think that's all) in sizes that range from the smallest, about the size of a dried navy bean to the largest which comes close to a small hen's egg.
This is Yakima Bait's pre-tied version of the Spin N Glo rig.
Here is another version tied by Yakima Bait and designed by the late Roy Houle. This gives you an idea, good or bad, of some other means of floating a crawler harness. When I was introduced to "floating spinners" as we called them, we'd also take a worm blower and give the crawler a shot of air.
And this is Luhr Jensen's version using an Okie Drifter for a body.
While RPS likes a single hook to reduce snags, two small hooks in tandem are also relatively snagless and possibly weigh less than some long, single hooks. The hooks used on the above spinners are large in part because of the size of the walleyes in the region and the belief that the larger Octopus hooks would hold better than smaller hooks.
Finally, here is Mustad's new version of the Slow Death hook. It's designed for use with plastic baits, and that is why there is such an exaggerated bend. Sorry about the soft focus, but I figured that the bend was more important for visualization than the point. We've all seen points.
For those not familiar with the idea of a slow-death hook, you thread half a crawler up the hook past the eye. The half crawler then spins like crazy when it is slowly trolled and has two things that walleyes like: motion and scent. I don't know the theory of why such a strong bend is needed for soft plastic, as I haven't had a lot of problems getting plastic to spin, but somebody likes it.
