What plane do these parts come from?

Hi their,

I recently bought these pieces and I need a bit more information regarding what plane they were from.

I have a cone lense which says this;

14" cone 14a ref No 2312 serial number k4 2422.



I also have a camera which says,

F46 body unit 24 volts 14aa/1768 serial number NoCC 54 o. On the other side it says f46 protective cover ref No 14a/1100.



I have bought these for my father for Christmas, it would be great if you have any information for me.

Best wishes,

Ryan
