Hello,The Erard 3443 was probably built in 1906 – 1907.Some people call this model “Louis XVI”, but I think it is rather ‘Louis XV”There has certainly written “13, rue du Mail, Paris” ?In any case, it is a very beautiful model!
Are you buy any chance selling your Erard Gothic. I am restoring/rebuilding mine and am in desperate need of spare parts. Please do let me know if your keen.
