can somebody help me on some info. I have a few Borden Krylons laying around and I want to know what years that Borden break down by the category because the cans that I have dont have a date on them, ie: i got a Avocado with the avocado sticker on it with the # on the cap, a chrome yellow with the # and name plus a barcode underneath the name on (on the cap),just to name a couple. also these cans have a strange symbol or number towards the bottom rim. I understand that borden can break down to the rust magic series, notchtops,barcodes but how can you tell anything from the 60's until sherman williams datewise because these cans dont have dates on them and im confused as fuck
