Try the Westmorland Gazette. Reception of clear wireless in the Windermere area would be a big thing back then and everyone would be talking about it! It's been over twenty-two years since I was out mobile with the BBC Transmitter Team, but one of the things we did was to pop into the local dealers occasionally for a cosy chat and to see if there'd been any problems.

There was a dealer in Ambleside but can't remember who it was. Maybe worth a Google to see if any still exist - there may be someone old enough to answer your question.
