Rotary Telephone Handset (Wilstone HP23)

This is a "retro style" telephone handset that looks like a traditional pulse dial phone. Although it is operated in the same way it actually generates DTMF codes for compatibility with current telephone lines.
I have not had a home telephone line for about five years so not been able to use this. It certainly worked when I packed it away back then and I have every reason to expect that it will still work - but no way to prove it.
