Haegar wash basin and pitcher

I love to collect vintage pitchers and basins. This is a vintage Haeger wash basin and pitcher that are number 4058 for the pitcher and basin is 4060. I got the set for under 6.00 thrifting the other day. After some research I learned that Haeger basins and pitchers numbers don't match. Usually with most pottery pieces, both numbers will match up if there is more than once piece. I thought was quite interesting.
