Ever ready brush

As I've mentioned before I have an old ever ready brush a C40. I really don't know when it was made I just can't remember when dad got it and after dad I got it and i'm 65. I got it in my mind to buy a couple more like it and it thought a ever ready C40 would be the same. It's not. There is a little difference in the brushes and they must have made them for many years because this box has a bar code on it. I know when my old one was made there was a bar code. The brushes look almost the same except that the old one has a gold ring where the bristle and plastic meet. of course the bristles haven't been used so I hope with use they'll get better so if anyone out there buys a vintage brush just make sure if possible that it was made in the era your looking for. I have one more C40 coming I know that the boxes look different so maybe this one will be of years gone by.
