Old Practical Wireless article wanted
 

Hi, I'm looking for an article that was in an old Practical Wireless
magazine about early to mid 50's it was about a simple two valve HF
transmitter, it was unusual as the chassis was made of Hardboard!! I'd
very much appreciate a scan if anyone can find it, or possible an idea
of the month and year of the article, thanks from Ron G3YUH...
