I thought I would do the seller involved a favor and let them know, especially since it is a vintage camera seller who has the current listing. This is the reply I got within just a few minutes of notifying them.

"Dear lab16,

I understand.
Propblem is that item specifics are provided by ebay. It is not from my item description. And by new ebay rules I can;t list item on ebay unless I use item specifics.
So that is where this error coms from,
Rokas"

Appears that once again eBay is making ridiculous rules.
