Hiller Construction numbers...

[Centurion]

Hello Hiller operators,

Hey Folks, does anyone have the book that list the Hillers by construction number? I need it to try and get a replacement data plate. The Army serial number of my Hiller is 56-2300 made in 1956 and I believe the C/N is 917. If anyone could add any additional info I would appreciate it!

Thanks,
Dave
