Looking for a spare canopy (Nimbus 2C)

Hello,

I am looking for a spare canopy for my Nimbus 2C. I need it in order
to do aerial photography, my camera is too big to go trough the
window, so I must drill a larger hole. So a damaged or second hand
canopy would be great!

Do you know where I can find such a thing? Do you think other glider
canopy will suit the nimbus 2c (? cirrus ?)

Thank you for your help !
