I have just purchased 1.5mm brass sheet to make side tanks for my 5" gauge Speedy. Should I anneal this prior to bending the 3/8" radius bends.

No. If you do, you'll end up with Pringle-shaped brass sheet. It will really soften it and it'll be much more difficult to get the flat bits flat again. There'll be no strength to it!

3/8" rad should bend well in the "half hard" state that brass sheet is normally supplied. Try it out on a bit of scrap first (assuming you've got some!)

Good luck – and remember to measure twice before cutting once….
