It was fortunate timing on my part, as I happened to be visiting
Seattle so posted locally to Rich. The return was to the UK & the cost for
delivery was minor.
Alternatively, if you are in the UK contact Greenham Regis in Lymington, There was a great guy, Andy Haines who retired after Greenham Regis was acquired. He has a whole lot of old spares and does some
repairs on the side. They may have his contact details and he may have what you are looking after.
