This is another variation of a Spratt LRI, this one embossed: Patent/Feb.5.1850 This is an embossing variation to the last one I posted; [id=208195248] This is my type 'B'. The right side of the tab points towards the right edge of the letter E in Patent. The arms on the letter E in FEB are short. The 5's are poorly styled, almost comical. Height: 1 3/4", and 1 1/2" across the base. Color, typical dark green. Unknown previous ownership.
