This small organ is the work of the British organ-builder Sir Thomas Casson. It dates from 1904 and has the opus number WO 605. It was first installed at the St. Peter & Paul church in Willington, England, where it remained in service until 2001. The Israeli organ maker Gideon Shamir, visiting England at that time, heard that the church of Willington wanted to sell it and took care of all the necessary formalities.

Shamir installed the organ in the Monastery of Latrun, and the later was inaugurated for a second time, after almost 100 years, on the 29th of June 2002.
