Sieg A0 tools please?

I have a a Sieg C0 and need to find good quality tools and spares for it.

I see there are some tools for it in the accessory section, but are they top end quality?

I really need a specific parts list with numbers to find from current manufacturers, rather than trawling ebay hoping to find something that might be correct, guessing as to weather it’s the right thing.

I don’t mind good used parts from Emco 3/4, but its not exactly reliable is it?

Where ever can I get a 1/4’’/6mm Jacobs tail stock chuck? Or the best low profile four jaw chuck?

A four way tool post with quick change holders?

What does an ER16 collect chuck even look like?

I only have a single tool post and need to source everything.

It’s making me reconsider selling to upgrade to the next model which has plenty of parts, but this is the ideal bench top size for small scale models.

You can probably tell it’s starting to wind me up, so would appreciate some help!
