St. Helen Bishopsgate, London made in 1995
The church was affected by two IRA bomb blasts, which brought about the restoration of the church. The west gallery was restored, with the organ removed from the east end to its original position.
This organ is a combination of restoration, reconstruction and new organ. Of the 1743 Griffin organ the Great/Choir chest survived with the original upperboards for the three shared stops. The case was reduced in depth close to the original, and the pipes were repaired and the original voicing restored as far as possible. The missing stops on Great and Choir were copied from the originals, the Sesquialtera's original composition restored. The Swell chest and box are new, the compass extended from the original g to C. The stop list is England's of 1810 (which added a Dulciana and took the Fifteenth out of the Cornet). the Pedal is also new, and is based partly on the Gray & Davison Pedal Organ of 1851 at St Anne's Limehouse.

Stops marked * contain original pipes from 1742/3. The Swell Fifteenth and Choir Cremona contain England pipework from 1810. The other stops are new.

The compass is GG - d3 long octaves for the Great and Choir, C - d3 for the Swell and C - f1 for the Pedal. The pitch is a1=440Hz and the tuning was developed by Mark Lindley for the performance of Bach's music, an elegant and mild circulating irregular temperament.
