You're kidding, right? In the Nikki carbs, we will rarely find 91, mostly find 92 and in SA carbs we find 93. In the Hitachi carbs, it ranges from 94 up to 106 depending on the year.

It's sad to see that those parts were all stored outside in the rain. There is a lot of value here. The 13B manifolds can be studded in the Nikki pattern with channels cut to mimic a 79 12A manifold, and used on a 4 port 13B with great success. I would look for healthier (not rusty) studs, but the aluminum casting itself looks mostly ok. And the Nikkis still probably have some good venturis and other raw internal parts that could be used as spares if someone wants to start experimenting with hogging Nikkis.

This would be quite a nice haul for anyone looking to fast-track into it. Even that old blue air cleaner lower section can have its vertical sealing part removed and used as a perfect base for a carb hat when doing a Nikki blow-through. I've done it, but only with old messed up rusty or bent air cleaners. I'd cringe if I had to chop up a good one.
