Linking up today with Sophie at Her LIbrary Adventures
Also, Regina Everdeen - Harpiste of the Netherlands,
maintains a wonderful website devoted to the Wurlitzer Harp with a special page that lists all known numbered Wurlitzer pedal harps.
She has very kindly included information about Lois' harp here here.
The full list of known Wurlitzer harps can be found here.
Regina's website can be found here.
Thank you Regina!
