I'm still sorting my way through machines...deciding who will stay and who will be adopted out....But, as I was trying to decide between the two 99k's I realized that the serial numbers on both machines are from the same run....just 3620 machines apart....What are the odds...one machine was bought at auction here in Pratt and the other came from a yard sale in Ft.Riley....so for now, they both stay....both machines came from the run authorized on 11/23/55...and both of them are in their original cabinets :D
