Here is another Spratt LRI with serif embossing. The embossing is: Patent/ Spratt// 1850. This one is from an obviously different mold than the last two I posted. The last one is found here: [id=211133227] This one is not so blue in person, and is more of a deep aqua. The tab on this one is smaller than on the LRIs in the two previous photos. This shorty is likely an underpour. It stands about 1 1/2 " tall and 1 9/16" across the base. Unknown previous ownership. Through hole diameter is 3/4", smaller than on the previous two Spratt LRIs.
