Friends, Restorers, and Suppliers

Some Interesting Websites

Martyna Kazmierczak is our very special Friend, and we will always remember her enchanting performances at our Finchcocks parties.

  She has just launched her own website - make it one of your favourites for regular visits:


The website of the Pooya Radbon Collection of Early Keyboard Instruments is now up and running.




Ralf and Heiko Hansjosten are building a new website with details and pictures of their collection of instruments.


Note that search engines may tend to push you to 'klavieratelier'.  Be persistent!


There are several professional restorers operating in the UK; those mentioned below are those that I know personally, and who have agreed to be 'linked'.


Lucy Coad

Lucy also operates an on-line shop for items that we frequently need.


John Broadwood & Sons Limited - the longest-established of all the piano-makers - is still active, and happy to undertake reatorations of Square Pianos.  Especially Broadwoods, of course, but other makes will also receive sympathetic treatment.  No email or website, but please write to Dr Alastair Laurence, John Broadwood & Sons Ltd, Lythe, Whitby, North Yorkshire YO21 3RT, or telephone 07770 772233

The Galpin Society has been established since 1945 for those interested in the history of musical instruments. Also a very good lead to a variety of interesting websites - including this one!

We owe a great debt to the Auction Houses, who receive us courteously and with understanding. They allow us to study instruments -often historic - before they 'disappear' into private ownership - or even abroad.  We do purchase (or even sell) through them occasionally, but very often we are just there to share our enthusiasm, to record detail, and to meet each other.  

Piano Auctions Limited run four sales every year at Conway Hall in London, near Holborn.  Square pianos are usually well represented, with occasional 'cabinets' and even early grands.  Many of the squares sell for 'affordable' prices.  We always have an informal meeting of Friends of Square Pianos on the day before the Sale, and enjoy lunch in the nearby Dolphin pub.  See you there?
