In 1977 Mr. Jacob Muscat bought from the Immanuel Church of Jaffo the old Walcker organ which had been there since 1904 and had been practically unplayable. Gideon Shamir entirely rebuilt the instrument and adapted it to the salon of the old apartment of J. Muscat, then readapted it to his new salon when the latter moved in 1993. The original organ contained eight stops. The considerable height of the salon led G. Shamir to place the Swell stops above those of the Great. Also, he added three new stops, a Regal to the first manual, and a Rohrflöte 4′ and Blockflöte 2′ to the second. The two pedals which open and close the Plexiglas swell are also a modification of G. Shamir, as well as two buttons designed to regulate whether the Regal coupled to the Pedal would be used as 8′ or 4′.
