    Normal 700c inner tubes will be fine. The difference is quite small (622mm v 630mm). In fact I think some of them are marked 27".

    If you've ever tried pumping up an inne rtube when not installed in a tyre you'll realise just how big they go before they go bang :)

    for example, a 20" bmx tube will go over a 26" mtb wheel if pumped up enough!

    is it worth replacing the rim tape, its about 30 years old doesn't appear to have degraded no rips e.t.c. I know its not expensive but if its not needed then that is best as money is very tight.

    yes replacing the rim tape would be best, you can do this for as little as £1 a wheel with some velox rim cloth, as for 27" tubes keep an eye out for a website arriving soon called www.innertubesdirect.com they will have every tube known to man, including pushcair tubes! :P
