Campy's little gem

I'm in the cleaning mode attacking my Campagnolo Nuovo Record Gruppo. Labor intensive but fun at the same time. I found an interesting item burried in my tool kit...

Packed in the small clear, circular, plastic case are Campagnolo bottom bracket bearings (I believe) from the early eighties? It's a joy to smell the familiar grease and inside are 2 sets of 11 ball bearings sitting in a retainer ring. I bought this little gem in the early eighties from a bankrupted bicycle shop in Edmonton. Now, I wonder if I can use this to my restoration? It's a fun discovery!
