I've had this one for decades, and I've seen these 3-pc covered bouillion or porringer sets in museums several times in Europe. The story is as charming as is the old pewter and maker marks: these were a traditional gift to a new mother for her 'lying in' period, c. 1700s, when she was often taken care of and brought her food on tray. "Ecuelle ou bouillie de accouchée". The covered porringer bowl kept her food warm longer so baby's interruptions were less disruptive in her nourishments. These very early ones are very rare to find complete with the 3 matching original pieces and are museum quality sets. The full measurements are noted on photos.
Very good to excellent condition for age and type. No bends or breaks. Beautifully crafted - old pewter. Rare display set, not to be used to eat or serve. These were originally a French tradition but I've seen some claim origin in Poland, and I can't find this particular maker mark. When purchased from a very reputable French seller, it was identified as French, mid-1700s. I know of one other for sale at $1200 at listing time.
