Here in Australia a very popular cake called a nutloaf was made in a cylindrical cake tin in the 50’s and 60’s and is making a comeback now.
It consists of a sleeve of metal (the ‘tube’ ) which is rolled up and sealed by two metal end caps with small steam holes in them. To bake you put it together, fill and stand it up on it’s end. Cakes come out a lovely cylinder shape and are served sliced into rounds and buttered.
Here’s an example: http://www.tablepride.co.nz/cs/prodDetails.asp?idproduct=1935
I have never made bread in one though…
Hope this is of some use!
P.S. Slightly off topic but if you or anyone you know is going down the ‘cut off the crusts please Mum’ stage like I am at the moment… I just got my hands on these super cute sandwich cutters - the puzzle ones are a HUGE hit (the leftover crusts get frozen for use in meatballs, meatloaves, crumbed chicken etc!)
