From "The Tracker" Vol 28 No. 3, 1984: "Philip A. Beaudry & Co. of Lowell, MA., have completed renovations and tonal rebuilding of the organ at Holy Rosary Roman Catholic Church, Lawrence, MA. The organ's exact original provenance is unknown. The Lawrence Tribune reported on an unknown date in 1934 that the organ was dedicated in 1910 by Pietro Yon. William Laws removed it in 1933 and returned an organ of 3m in 1934, built on old slider windchests with electro-pneumatic pull-downs and stop action, having an Austin-style console, and containing pipes bearing the opus numbers of two E. & G. G. Hook & Hastings organs built for other locations: in the Swell and Great, pipes of op. 599 of 1871 listed for Asylum Hill Congregational Church in Hartford, Ct.; in the Choir, pipes of op. 523 of 1870 listed for Heiskell Methodist Church in Philadelphia. Mr. Beaudry reports that the Swell windchest had received three new stops prior to 1934 by the addition of channel blocks and sliders on the front and back, and that most ranks had been enlarged in scale by one pipe. His firm revoiced and re-regulated the pipework with some inter-divisional exchange of ranks, replaced a missing mixture rank, added a 16' Trombone to the Pedal, and refurbished the existing mechanism."

Identified through online information from Joseph R. Olefirowicz. -- Carvings on the pipework helped solve the mystery of the origin of the instrument, after the 1934 Laws rebuild and installation into the current church. Robert Reich pulled the bass pipe of the Great Fifteenth during a touch-up tuning before an organ recital, and found the Hook's opus number and year carved into the pipe. E. & G.G. Hook & Hastings' Opus 599 was originally in Asylum Hill Congregational Church in Hartford, CT. According to church records there, a new organ replaced this instrument in 1911, but there is no documentation about the instrument between 1911 and its appearance as a new installation by Laws in Lawrence, Massachusetts. This information can fill in the blank to the II/30 organ at Asylum Hill Congregational in Hartford, Connecticut (1871, Opus 599, E. & G.G. Hook & Hastings) - whose documentation of current location is incomplete.

Identified through online information from Joseph Olefirowicz. -- Restoration of rebuilt E. & G. G. Hook & Hastings. A common "victim" to Laws electrification ca. 1930, this organ was completely restored by the Beaudry Organ Company in ca. 1984 and is in excellent playable condition. - Its roots are presumed to be of Hook origin. The entire organ is under electro-pneumatic action, with a faux facade at the back of the church in the choir loft.
