I aksed Peter off-list what tyres he would recommend, and he told me that any of the Japanese 27x1's which appear on eBay from time to time will be fine. He sent me the following url of some currently on eBay in the US as an example (but as Peter, told me, you can search for '27" tires', and make sure they're 27x1):

This link worked for me, but let me know if you experience a problem.

By the way, you need to be sure to get suitable brake blocks for steel rims, and be aware that when wet, steel rims can take more stopping than in the dry.
