I have taken one of those off in the past (it may be sitting in my loft still), so I probably have a tool for it, but unfortunately, I am in SW9, so not terribly helpful (unless you can get to KT1 during working hours).
You will find when you get this off that it is on a threaded hub rather than the more modern splined hub. This may mean that you can just stick a freewheel straight onto the thread and you are good to go (once you've sorted out your chainline).
Need to go up to the loft later, so will have a look to see if I still have that cassette (EDIT: before I get flamed, no, I do not mean cassette, I mean 5 speed freewheel) and see whether I can work out if it can be dismantled / spaced.
