Default Missing part questions about Yuasa clone of Hardinge HV-4 5C indexing fixture
Hello,
This Yuasa copy of the Harding HV-4 5c indexer fixture was purchased via the internet.
upon arrival it turned out that some parts were missing.
I don't know the name of this part, but it is the disc with the notches where the spring pin of the dividing disc falls to prevent the drawbar from turning loos., in stead a solid aluminium sleeve was mounted.
inside the disc that is retrachted by the lever there is a concave shape, that must have some purpose, but sins i dont have thease parts , it is unknown to me

So I'm looking for this part or images of it so I can make it.
A clear exploded view where these parts can be clearly seen would also help

Thx,
Ton (ak HK51)

Maybe you can more clearly identify the part from this: https://aafradio.org/garajmahal/HV-4N.pdf
