Value of Reel Push Mower?

I purchased a used reel push mower in 1980 to use to cut the grass when visiting relatives buried in the cemetery. It has a 14 1/2inch cutting blade, five blades and the wheels are Pennette Ball Bearing #Z101-SN R1510.A.14. Does anyone know the manufacturer, its current value, or where a spare part can be obtained when needed? Thank you!
