A beautiful case - I saw it a good few years ago and was impressed. Unfortunately, the organ hasn't lived in it since the Binns rebuild of 1926 (it was originally by Gern and may have had an unreliable pneumatic action) and has not been fortunate since. You can see it skulking in the north aisle to the right of the picture.
I've looked hard, but cannot see any reference by OrganistOnTheHill to the location of the organs he mentioned. For those who have not twigged his name, the organs mentioned are at Harrow School Chapel and St Mary's Church, Harrow on the Hill. The fact that I grew up in the same town is completely coincidental...
Back in 2009 I made a post ("Interesting Organ Project in Poland - https://mander-organs-forum.invisionzone.com/topic/2384-interesting-organ-project-in-poland/ ) where I referred to the destruction by fire on 9th June 1979 of the organ (1752-61) by Michael Engler in the church of St. Elizabeth, Wroclaw, Poland. At the time I made that post there was a fundraising effort in progress with the aim of building a direct replica of Engler's organ for the church in question. I thought I would post here, for the benefit of anyone interested, an update which I noticed online this afternoon.
In December 2017 a tender was issued for the work - http://www.opusorgani.pl/more.php?ch=3&subch=3&article=9 - in which photos are included showing that work to reconstruct the organ balcony (which was also lost in the fire of June 1979 along with the organ). In May 2018 it was announced by Fundacji Opus Organi - http://www.opusorgani.pl/more.php?ch=3&subch=3&article=10 - that a contract for the work on the organ has been won by a consortium. The consortium doing the work will be lead by Orgelbau Klais (Bonn, Germany) and the partners in the consortium will be Manufacture d'Orgues Thomas (Stevelot, Belgium) and Zych Zaklady Organowe (Wolomin, Poland). The contract was signed on 24-Apr-2018 and is effective until 28-Feb-2022 with the price being PLN15,996,120.00 (net) but, with VAT, that becomes PLN19,675,227.60 (around £4,000,000).
I should think, and hope, that with a consortium like that, the long process of the work will result in what should be a first-class reconstruction of the lost Engler organ which, among other things, will no doubt include pipes built with metal specifications similar to other Engler instruments. It should be well worth hearing and I look forward to seeing the outcome.
Hope this has been of interest.
