Anyone Recognize ID these Shimano 333 caps? what bikes would they be OE to ?

[Lamont]

Shimano 333 Black and with chrome tip caps of some kind....

Stumped on what these are .... What they are called and what the belong to ...

They looked to me like valve stem caps , but the thread is much wider.... way to big for a Schrader valve stem

Could they be hub axle caps?

What bikes would these be OE ?







(Part of a NOS random parts bin that has several items that I do not recognize ..... #Bob McCallister / Wonderama / What the Heck is it ? )

Looks like the early stem shifters. But obviously not.
Next guess would be some kind of axle cap (size is for front) .

That is a derailleur part. Early Shimano 333 derailleurs had that little nut thing mounted on the pivot bolt on the derailleur, Sort of like a derailleur guard. Let me see if I can find a picture of it mounted to one.

Ok, best I could find. First is a Sturmey derailleur with the same peg, which is just like the Shimano 333 derailleur. Second two pictures are the Shimano 333 derailleur with a shot of the threaded part where your pegs part mount.

Now that I look at the red derailleur again, it doesn't saw Archer on the name plate, it is Archery. I see the 333 in front of it now, so that must be another variation of the 333 derailleur.

My mid seventies Bridgestone touring 10 speed had one of those on the derailleur side of the rear wheel, as the wheel nut. I figured to protect the derailleur if the bike fell over.

they would look sweet on bolt rears as axle caps as well ..... could even do both sides for symmetry look.

real tribute to shimano for the innovation / evolution ..... recognizing the need for break away rear mech protection prior to derailleur hanger frames ........ ( ive got an early shimano disc brake system here from c 79 that also astounds one for the before its time-ness) and also a flash in the pan.

Id like to buy / get thread checking tool / or a rack like the hardware store.... now to see if the thread on these is 3/8 26 tpi or M 10 ..... or something else ..... they seem to tread on period 27 in axle correctly , but have to verify
