I spent a lot of time trying to id this same melon ribbed planter. Quite a few companies made similar. I ended up narrowing it down to Red Wing 276 or Camark.  My blue Red Wing had a ridge inside and rim and my yellow Camark did not - so I would guess yours is Camark but you might want to do some more checking.
