Sorted Shimano Biopace Chainrings (SORTED)

My Shimano Biopace Chainrings are getting worn, so I'd like the following:

Shimano Biopace Chainrings:
28T 74mm BCD
38T 110mm BCD

These chainrings are for the inner and middle for a triple chainset, I'd preferably like silver not black chainrings.

Obviously, the chainrings will need to have good teeth.

If you have a whole Shimano Biopace triple chainset, I would be interested.

Thanks
Guy.
