These nuts still available. They were difficult to remove and went back on very tight.

One spoke at 11 o'clock, does not look to be pulled fully into it's slot.
never mind that the next one is missing!
The drum looks original but the spoke flange appears to be a reproduction one with a very shallow "dish" to it. It would be interesting to try to insert an original outer side spoke without loosening off the drum.
Those are aircraft split lock nuts........mostly used around the engine bay area to cope with heat. They have been silver cad plated which is non standard as aircraft hardware has a more gold yellow colour of cad plate. They don't tend to use normal nylon type nylocs around aircraft engines as the excessive heat will melt the inserts. I've seen these nuts available in sizes from 4 BA up to around 3/8" and mostly in BSF threads........they work well although the "Biting action" of the split locking can be quite aggressive on the bolt threads........almost singlar use, quite typical of aviation bolts/nuts on early British planes.......these are nothing like American AN hardware of the same era.........Sorry just some useless info.
Oh well...
Btw, best for keeping your Nuts tight on your bolts.....
Nord lock rings, or Locktite, mind the grade.
Cheers, and up to silly Monday!

Funny to see all that hassle some here seem to accept just for not using Loctite on standard nuts and bolts - for even safer joints. Not even visible to the public, so why looking for all sorts of contraptions just to avoid thread lockers. Certainly you select the suitable type of these , mostly the low strenght or max. normal strength, otherwise you need heavy tools for disassembling later. Nylocs are not safer than low strength Loctite and friction in threads is same, so what reason for not getting Loctiite and all ??
These "aircraft" safety nuts look like mangling threads when assembling or undoing them. No problem when exchanging the set - but I guess today you don´t bin BSF fasteners after one use only ?? So once more a good idea to have Loctite on threads, they will stay perfect for many times.
