I wonder if I could comment, please, on the Bridlington Priory thread?
Some have commented on the mixtures; here is some information about them.
Sadly there is no Anneessens chorus mixture. Anneessens supplied a Cornet 2-4 ranks for the Great and a Mixture 5 ranks on the Swell. The Great Cornet largely remains, fleshed out into 4 ranks from middle C by Compton in 1949, and now by Nicholsons as 5 ranks from middle C, replacing the Compton rank by a more appropriate one. Of the Swell Mixture only the Twelfth rank remains, made separately available in 1968 when Laycock & Bannister added a new Swell 5-rank Mixture.
In 1968 five new mixtures were added: Great 19.22.26 and 29.33.36; Swell 18.104.22.168.33; Positive 26.29.33; Pedal 22.214.171.124.
To later ears (certainly mine) many of these stops were both pitched too high to start with and broke back irrationally and too late. Consequently they stood away from the rest of the flues and only became almost tolerable when the Great reeds were all drawn. Even then the Great Cymbal sat hopelessly on top.
My suggestions were to scrap the Great Cymbal and replace it with the Positive Scharf (too high to sit on top of the Postive chorus which, typically, had no 2ft Principal - such a central rank for a Positive with pretensions to a principal chorus), to remove the top rank of the Swell Mixture (the 33rd) and to rethink the breaking pattern of all the manual mixtures so that each broke back early enough to reach down to and reinforce the chorus with which it is designed to work.
This has been done, and I believe the resulting choruses are really splendid, the full coupled flues possessing tremendous richness, depth and complexity, with plenty of natural brightness.
The 32ft Tubasson totally dominated the organ until the recent work, when it was moved two bays east and thoroughly repaired and regulated. It now blends in very well, though - yes - has sadly lost in the church some of the animal excitement it used to possess. Still, the general gains with the rebuilt organ [by improving the layout] are so huge that this one slight disappointment has to been considered in context.
I would be so thrilled if folk come to hear it when I give a concert at Bridlington this Saturday (29th July) at - NB - 6pm. The programme is designed to show as much of the organ's colour as can possibly be displayed in one concert and included Bach's Zei Gregrüsset variations as well as the Willan Intro, passacaglia & fugue, Franck Chorale I, Howells 'Master Tallis', Vierne's 'Clair de Lûne', a Fanfare by Cook and some variations by Dandrieu.
