Does CUPPINI rear luggage carrier 23466500 fit Primavera?

Hi all

I am new in SIP and in this forum, and about to make my first purchase, a rear luggage carrier.
I hope I placed this post in the right section.

I have two questions regarding Art.No. 23466500 (Luggage Carrier rear, CUPPINI)

1) will it fit classic smallframes (such as Primavera and 50 Special)?
In the item description those models are not specified, but there are other newer smallframes like the PK, which are similar in shape.

2) Is this item available in Chrome? Or only in Black?
Thanks a lot!
Ruggero
