Don't do it!

Kodak Box Brownie - No 2 Cartridge Hawk-Eye Model B
Snappy naming! Looking around for inspiration for today's picture, this old camera has been sitting high on a shelf on an old wireless. Made in Great Britain between 1926 and 1933. Not sure of the history - think it was Mum's and it must have been handed over to me at some point for some reason.
The temptation is to run a film through it - 120 is still available. Just no!
