I recently picked this amber capacitor up in a small collection. I have seen these in the large shape, but not in this small version. The glass portion is about 3 1/2 inches high. The width of the glass ribs is 1 3/4 inches; the width of the glass base is 1 3/8 inches. The hardware is in great shape. Are these small ones common or uncommon? Any help on rarity and/or value is appreciated. Thanks in advance.
