you are right, it is amazingly hard to find a picture online of the flame canon! Unfortunately, I can't actually help you as my canon came 2nd hand, therefore missing bits, even the horse and cart... so I made a best guess with the parts I had... I'll try and post a few closeups, if it helps you decide what to use... in the meantime I did find this single picture, with the bellows, on the ground... looks like this person didn't know what to do with them either.
