    Thanks!

    I saw one for sale in Europe for 13,000 Euros and it is unrestored. I do not know if it is too loud for the home. I have it in my church which has a fairly large sanctuary and I don't think it loud enough. It is probably ok in a home environment.

    Does anybody know if the size of the suction blower makes a difference? I do know that 1/2 horsepower is the recommended for an organ the size of this one. I do not know the horsepower of the blower that is connected to it. It doesn't say anywhere on it what it is. Well, that I have found yet. All I know is that it is a

    Another question. I want to change the Silks. It looks like a few holes have come in them. What kind of fabric is used? What is original to it is a simple weave really thin Black fabric. My sister thinks that it is a cotton fabric. I have read that "Poplin" or "Broadcloth" is what is used. It seems too heavy. My other M&H has perfect silks and they seem to be similar but brown.

      I have two of these old ones (not quite as classic as the one discussed here though) both with two manuals and pedals working the trackers as described. The one is an 1880 Jilles van der Tak which is a pressure organ and has a tremedous volume. It can be fitted with a blower and once upon a time had a pump lever but works very well with the treadles, albeit eliminating the use of the pedals as the appendices to the lower legs of the player are obviously needed elsewhere....

      The other one is a Mannborg Church organ fitted with a 1/2hp blower and pump lever still intact. This one was used in a church of roughly 35 X 20 metres and with a balcony. The padre complained that it did not have enough volume so changed it for an electronic organ providing louder noise. This is a suction design but also has plenty of volume. This one is my avatar picture.

      Both of these I would recon have more than enough volume for a small hall.

        Oh, no! I found a hole in the bellows. Yes, they are still present. I reckon the old hand pump mechanism is still there. Great! I wonder what the practice foot pedal looked like?
        I will post some pics after choir practice.

          My mother and aunt changed the silks back in the 1980s on my grandmother's organ. They used broadcloth on the organ. However, if you're interested in something that allows more sound to get out, you can find acoustically transparent cloth in various colors. Parts Express is one of the vendors others have recommended and there are others.

          Hope that provides the information you need.

              I am no expert, but it looks like the blower label says it is 8.5hp, and uses 400Watts? The other numbers refer to the specific blower. Alternately, one of the numbers could be referring to the cubic feet of air moved per second or minute.

              After looking at other labels online, it looks like it is 400 cubic feet per minute at 8.5 ins. (inches of wind?). Inches of wind is the inches of displacement of water in an "S" tube at sea level.

              I hope this helps.

                8.5" wind is enough to ruin every reed in that organ! Especially the irreplaceable 32ft pedal reeds.
                eek!

                  I think that might be a "3" instead of an "8". That would make it 400@3.5

                    Cool! More pictures. I still think it looks menacing and marvelous. What were the measurement units back then? 400... CFM? 3.5 PSI?

                      My reaction exactly when I saw it! I've never seen that kind of wind pressure except in a pipe organ. It made me wonder, however, never having seen a 3m/p Mason & Hamlin, there was a part of me that said, "Well, maybe they need that amount of supply for that many reeds? No wonder the bellows have a hole in them!"

                      I've magnified the photo, and I believe you're probably correct. It is a 3 instead of an 8.

                      Sorry, hope I didn't give anyone a heart attack!

                        Call 911 (international)...... I think I am going to use the blower I got with my Mannborg giant for something else...

                          3.5" of water column. It is equal to 0.13PSI.
                          3.5 PSI would kill every reed, faster even than 8.5" water column. 3.5 pound/square inch = 96.88 inch of water!

                            4" is suggested for one the size of this one by what I have read. I know that it has been on this blower since before 1979 or so. That is when the owner before me bought it. It was being used in a Catholic Church before this.
                            What am I to do?

                              3.5" won't be that far off, so you should be good. Of course, you could always restore the hand pump!

                                Make sure it has a working wind regulator to protect reservoir and reeds.
