Looking at my Martin/King catalog (65), Martin had a #7 and a #8 "Perfection Round Bottom Pot" with those style ears (the catalog doesn't show a cover with the picture). It also looks like the catalog rbp has single hole ears with the bail facing front/back like yours. It also looks like they used the #7 rbp without a cover as a #70 planter pot 7"dia x 8" deep. Unless shown otherwise, I would say both pieces are Martin.
Same catalog/page, the Martin smooth bottom DO has 2 hole ears.
