I work at a thrift store and do the pricing,most things I have found by looking them up on internet however I am not having a lot of luck with this chair.The mark on the back has II on the top then 24 below that,then to the left 5,to the right p,and bottom k so from what i understand this would mean November or December 24 1877 parcel 5 class 2.the other mark on the bottom of the chair is James Reilly under that looks like Manchester.If you could help me be correct in this chair and an idea of its worth i would be much grateful.
thank you March
