First picture is of the inside of front most pin holder the part you see is where the metal plate goes if I had a spare to put in it would help you see easier but I dont so.. Second picture is a side view of same part & the 2 little humps you see sticking up are where the pins go through & how they wore or how they added material to themselves or how ever you want to say it.Like I said couldnt feel it do anything odd just tripped out how it did that,They were actually a bit more pronounced than that originally but my little girl was playing with it today.se if you can solve the mystery of the halloween hinge pin holder.
